Thermal conductivity

I don't believe the section on thermal conductivity, so I added a citation needed. Silver has the highest thermal conductivity of the metals. Nevertheless, I think it is unlikely that diamond is the only non-metal with a higher thermal conductivity. Carbon nanotubes, for instance, can have thermal conductivities estimated at 6000 watts per meter per kelvin according to Wikipedia. This is much higher than silver. My impression was that other crystals could also have very high thermal conductivities (e.g. the wikipedia article on thermal conductivity mentions sapphire, but the numbers there looked wrong) -- not as high as diamond, but higher than the metals. There are two ways to conduct heat -- ones that are related to electrical conduction, and ones related to phonons. The former are dominated by metals, while the latter by regular structures like crystals. It'd take a pretty good survey to conclude that only diamond has higher thermal conductivity than silver. 141.154.126.233 19:10, 9 October 2007 (UTC)

Unusual uses of silver include the manufacture of prosthetic noses. :-)

My goodness: that comment sells itself short, by appearing to have a link to Prosthetic nose. Follow the link, for an intellectual treat. --Jerzy 16:50, 2004 Feb 20 (UTC)

...without causing noticeable harm to more complex life-forms.

Is this statement acceptable? I see people saying that it does, and that it bonds to human cells etc

How precious is a precious metal?

Your text on silver lists it as the second most precious metal following gold. In your text on platinum, you list this as considered more precious than gold. Is the "consideration" a common fallacy as reguards regards platinum as a marketable quantity, or is the text in error in calling silver the second most precious after gold?

The article precious metal states

The demand for precious metals is driven only in part by their practical use; it is also driven by their value as investments. Palladium is, as of January 2004, valued at about half the price of gold, and platinum at about twice that of gold. Silver is substantially less expensive than these metals, presently at 1/65 the price of gold, but is often traditionally considered a precious metal for its role in coinage and jewelry.

but doesn't "price" iridium.

With that possible exception, we can deduce the following sequence among the 4, which may or may not be the absolute ranking.

1. platinum
2. gold
3. Palladium
4. Silver

The injection of "marketability" into the discussion may refer to the distinction between the use of precious metals as hedges against currency fluctuations (or economic disaster) and their industrial uses. That distinction may be worth discussing in precious metal. (My understanding is that gold prices rise during crises to levels that would reduce its use for, e.g. edge-connector-plating in printed-circuit boards for electronics, if those prices were sustained in the long run. Gold futures contracts are industrial users' means of keeping their business running despite such fluctuations.)

But IMO let's treat this discrepancy for now as just sloppy research, unless someone comes forward with the intentions of previous editors, and for now reflect those rankings in the respective articles. Unless someone wants to research iridium prices first.

Health Effects

Removed the following sentences because I believe they are incorrect:

• Silver is used in along with copper as an agent to remove algae in swimming pools in the United States by use of electrolysis.
• Some swimming pools do not use silver due to staining problems so they instead used copper-zinc colloids instead.

I can't find any information on the web about swimming pools being sterilized by the use of copper-zinc colloids.

I suspect the following sentence is also incorrect, but I don't know enough about the field:

• Copper is active against algae while silver is active against bacteria primarily due to silver's activity in the absorption of oxygen causing bacteria to oxidize on contact.

Bacteria do not oxidize, nor does silver readily "absorb" oxygen. Eric 03:28, 24 Jun 2005 (UTC)

hello Eric ! take a look at oligodynamic effect. michael

Yes, I read the oligodynamic page, but it doesn't say anything about oxidation. Why does the absorption of oxygen by silver and the resulting "oxidation" of the bacteria not have a similar effect on algae? Eric 17:57, 24 Jun 2005 (UTC)

Hello Eric ! What do you mean by "oxidation of bacteria" and what do you mean exactly by "absorption of oxygen by silver" ? Silver-ions are interacting with some sulphur-containing enzymes and may therefore influence "respiration" of bacteria, and are "toxic" for silver-sesitive bacteria. Is this the effect you mean ? As i told on the discussion-page of colloidal silver, i made a (a bit quick and dirty) translation-attempt of my own webpage in german concerning silver and its oligodynamic effect.The link to that page is there. This text may help to find keywords for further investigation.

That was in reference to the sentence in the Health Effect section that I believe is incorrect. See above. Chemically speaking, it doesn't really make sense. Eric 20:22, 26 Jun 2005 (UTC)

The activity of some toxic heavy metals is the result of their affinity for sulfur, for example binding to sulfur in cysteine (Dartmouth Toxic Metals Research Article). Silver exists in one of its natural forms bound to sulfur so it also has affinity for sulfur (this article). I would assume this could pose a health risk, and perhaps explain it's "unknown" antibacterial activity (unknown according to appliance training on Samsung Silvercare laundry). However, upon reading an article about short-term and chronic toxicity, cyanide will be converted to thiocyanate in the body and does not build up over time, it may only cause immediate short-term effects in less than lethal doses. Is this a similar situation with silver?

There are health benefits in medical publications

I did a major restructuring of the health effects section. I removed the line:

• However, no clinical study has yet demonstrated a therapeutic use for silver as an antibiotic in vivo.

For I have found several studies claiming therapeutic benefits in vivo roaming around pubmed.

One of these is a study done on rabbits infecting them with herpes in the eyes and then dropping silver droplets either right in there, or after 20 hours. The study simply says under results: 'Prevention of keratoconjunctivitis'. It works. Many of the most recent entries in pubmed concerning silver only mention argyria, but I have not dug deeper into pre-1990 studies which should be much more common. Older scientific publications simply usually are not online, so the current medical library is biased to only the fashion of the last 25 years. And silver went out of fashion the moment antibiotics came into play.

I also removed the line:

Copper is active against algae while silver is active against bacteria primarily due to silver's activity in the absorption of oxygen causing bacteria to oxidize on contact.

Because the only source I could find for this is a site that immediately tries to sell you something. Also, there more than one possible process mentioned in the medical publications I read on the function of silver compounds in the body. It is also highly unlikely that the antibacterial function of silver is the same as it's antiviral function, and I can also find some evidence of this in the literature. I highly recommend keeping the explanation of the exact process open unless a credible source is cited.

Please provide sources for your additions. And sign your posts here.

I removed the following unsourced quote:

"A polymer protected form of silver, called Argleas, has been developed in the UK; it releases silver at a controlled rate, thereby overcoming the neutralizing effect of the ever-present chloride ions...this new form of silver has received approval from the US Food and Drugs Administration for use in antimicrobial dressings and with catheters."

If you have a source then reference it and re-insert. Thanks, Vsmith 12:59, 3 January 2006 (UTC)

The only contribution so far from the user who added this. Arglaes (note the spelling...) is a trademarked name of a product line of Medline Industries, Inc. - Reads like an advert anyway. Femto 13:22, 3 January 2006 (UTC)

• It appears to be a legitimate product, based on the number of hits in Google Scholar. It is, at least, the subject of genuine research. [http:// scholar.google.com/ scholar?hl=en&lr=&q=Arglaes+&btnG=Search] But as there are similar products on the market, I think this particular application is non-notable. Even if it is significant, I think it probably belongs over at Silver nitrate rather than here. eaolson 17:15, 3 January 2006 (UTC)

The sentence: ...However, no clinical study has yet demonstrated a therapeutic use for silver as an antibiotic in vivo... is still valid. i am observing every month medline for new entries. there is no known evidence for any in-vivo treatment using silver so far. Redecke 17:54, 3 January 2006 (UTC)

Silver exhibits antibacterial activity as seen in microbiology courses. It is placed on agar innoculated with a bacterial culture. The plate is incubated, allowing bacteria to grow in a solid lawn on the plate. The area around the antibacterial agent inhibits bacterial growth, as observed by a clear ring around it. Silver is antibacterial as observed in this experiment. As an antibiotic within the body I suspect there are probably health effects and is not used as an antibiotic (like many other antibacterial agents).

Silver Whiskers an Application?

If you follow the article on Silver Whiskers, which is listed as an application, you'll find that it is a failure mechanism of silver and other metals, not an application. Stifynsemons 06:33, 1 April 2006 (UTC)

Smelting

Ought there not to be something in the article about how silver is produced from its ores? Peterkingiron 23:06, 15 April 2006 (UTC) Who founded silver? —Preceding unsigned comment added by 69.18.106.74 (talk) 17:41, 13 November 2007 (UTC)

Antiwerewolf etc.

I've cut

* In legend, silver is traditionally seen as harmful to supernatural creatures like werewolves and vampires. The use of silver fashioned into bullets for firearms is a popular application.

... because werewolf and vampire articles say that neither mentions silver as a traditional weapon against them (except for a throwaway comment on Slavic vampire folklore saying that they were afraid of it, but not killed by it). Personally, I can't find any fictional refs to vampires and silver pre-Blade, although werewolves've been associated with the stuff for ages. I've replaced it with...

*Silver is often used in modern horror fiction as a weapon against certain supernatural entities, especially werewolves, who are sometimes described as being burned by silver.

... which puts more emphasis on the fiction and less on the legend. (I also moved it to the bottom of the list - it was i the middle of a load of scientific applications...) Tyrhinis 22:27, 14 May 2006 (UTC)

It'd also help if I realised modern fiction article doesn't exist. Bah. Tyrhinis 22:28, 14 May 2006 (UTC)

Just for the record, it's been suggested that both the "full moon" and "silver" elements of werewolf myth stem almost ENTIRELY from the Universal horror movie of the 1940's (see also The Wolf Man (1941_film)), and that neither existed in werewolf folklore before then (silver being a traditional bane of vampires, not werewolves). As such, I've amended that part of the article. Hossenfeffer (talk) 07:07, 17 March 2009 (UTC)

Kind-a-folklorish-sort-of

Forgive me for doing before asking – but I namechanged section Superstition to Folklore. I wish the story of Judas Iscariot to be moved from History to Folklore, but Superstition is an inappropriate (read: religiopolitically incorrect) heading for the (historically unattested) story about everybody's love-to-hate-Judas-Iscariot. Rursus 11:46, 12 December 2006 (UTC)

Silver bullets (as opposed to those made of other materials, such as the usual lead, or such phenomena as the playing of a silver flute or the ringing of silver bells), are among the few material objects (among the others, garlic and crucifixes) and natural phenomena (sunlight) that can destroy the Dracula character of legend. The conventions for the Dracula character are so well established that they cannot be altered without using literary credibility.

Silver bullets are also associated with another legendary character, the Lone Ranger of radio serials, comic strips, television shows, and one dreadful movie as a calling card.

These references belong in literature or pop culture; they obviously lack any scientific validity. --Paul from Michigan 02:01, 13 December 2006 (UTC)

Gas solubility

From my M.Sc. research I know that oxygen dissolves into silver rather easily. Attempts were made to create a membrane for filtering pure O2 from air. Shouldn't this be mentioned in the article? Like, under applications? -- Bakabaka 14:31, 26 June 2006 (UTC)

Picture of 'Vulva11' attached to spoken audio of article

Image 'Vulva11.jpg' was somehow attached to 'Silver.ogg' so I removed the audio from the file for until it is cleaned up. The large picture of female genitalia appeared directly over the beginning of the article in a very distracting and not entirely unwelcome (yet inappropriate) way. This appears on (at least) Safari 2.0.4 and would be visible in the HTML source regardless. —The preceding unsigned comment was added by 71.84.173.11 (talk) 10:08, 9 December 2006 (UTC).

I have been going through the links, through the source and through pages linking to the image you describe, but I cannot find how this page is linked here, maybe a strange browser error. --Dirk Beetstra ^{T C} 18:21, 9 December 2006 (UTC)

hehehe... that's quite a browser error then. :) It was definitely a deliberate popup, although I don't see it anymore. —The preceding unsigned comment was added by 71.84.173.11 (talk) 18:29, 9 December 2006 (UTC).

silver and laxatives

Hello, I just removed a comment about silver being used in laxatives, which is a use I have never heard of before and which I suspect is a case of subtle vandalism. If I'm wrong, feel free to restore the comment, but please cite a reliable source. Thank you. --Kyoko 15:02, 13 November 2007 (UTC)

Isotopes section

That last sentence is pretty weird. What is a "live short-lived nuclide"? And it would be better from a copyeditor's standpoint not to begin a sentence with a superscript number. I hope someone who knows what the sentence is supposed to mean will fix it. --Milkbreath (talk) 13:25, 19 December 2007 (UTC)

I replaced "live short-lived nuclides" with "unstable nuclides", since I wouldn't regard a half-life on the order of millions of years as short-lived. As far as the superscripts, the sentence would be read, "Palladium-107—silver-107 correlations..." Is that a violation of editing standards (which I admittedly know nothing about)? If so it could easily be written "Correlations between ¹⁰⁷Pd and ¹⁰⁷Ag..." A10t2 (talk) 18:16, 15 August 2008 (UTC)

Silver also inhibits viruses

It appears that in a 2005 study published in the Journal of Nanotechnology, silver in nano sized particles can prevent HIV from attacking cells - Study Shows Silver Nanoparticles Attach to HIV-1 virus. No mention that it actually kills the virus (unlike other hyped reports on this study). --Quatermass (talk) 11:02, 5 January 2009 (UTC)

Silver compounds

The section on silver compounds isn't actually about that at all, but merely a bullet-point list of wikilinks and references to applications. Given the importance of silver in multiple areas of human activity, a summary of the main chemical properties of silver, and the types and range of its compounds would be appropriate. Please help to replace the mainly off-topic bullet points with a more informative section. And Happy New Year, by the way. Plantsurfer (talk) 19:21, 5 January 2008 (UTC)

The article does no address a question I have; in normal tarnishing of silver, such as for silverware, what is the resulting compound of the tarnish? The article mentions sulfides, but I wouldn't think that sulfer compounds are normally found in household air. —Preceding unsigned comment added by 192.249.47.11 (talk) 17:21, 19 August 2008 (UTC)

In dentistry

"The malleability and non-toxicity of silver make it useful in amalgams for dental fittings and fillings." What?? This sentence is completely nonsensical. It is not the malleability of silver that makes it useful for this purpose, but the plasticity of amalgam, and its ability to set hard relatively quickly. Also the non-toxicity of silver in this application is more than overriden by the toxicity of mercury. I propose this section is removed until a coherent and accurate statement of silver's value to dentistry can be produced.Plantsurfer (talk) 23:57, 22 January 2008 (UTC)

Nice points. The original usage of malleability conjures to mind a hammer-wielding dentist cold working a silver nugget into a patient's freshly drilled cavity. Ouch! JaredAllred (talk) 19:15, 7 February 2008 (UTC)

In mirrors and optics

Are you sure that silver is the metal used to coat windows in architectural and motor vehicles? I bet it is more often aluminium. Citation please.Plantsurfer (talk) 00:04, 23 January 2008 (UTC)

In Clothing

This section (devoid of sources) was full of glowing superlatives and unsupported claims about the benefits of silver-containing fabrics. I toned it down. The language was reminiscent of claims made on the website of a major silver-fabric manufacturer (that website also glibly claims the silver confers electric and magnetic-field related health benefits). Therefore, possibly an employee or fan of that company had essentially "PR-ed" this section into a defacto subliminal ad. Rep07 (talk) 21:00, 28 January 2008 (UTC)

Biblical references

I have removed a recent additon by an unsigned in user, who inserted a number of references to the Bible. The bribe to Judas Iscariot is likely to have been silver coins, but even if it was lumps of silver, the reference does nothing to add to the article, as it merely demonstrates that silver was a precious metal (which we already knew). The Old Testament referneces are similarly comparatively trivial. I am removing these primarily because this is a chemistry element on silver as an element, and not the proper place for literary references. If the Bible (which i believe in) had provided information on its early occurence or use, it should of course be included. There are some biblical allusions to smelting and refining processes, which could properly be included in an article on that (but not here). Peterkingiron (talk) 20:06, 18 March 2008 (UTC)

Silver and Sterling Silver

Are Silver and Sterling Silver the same? The travelling cat (talk) 14:30, 11 June 2008 (UTC)

No. Sterling silver is an alloy of copper and silver. It contains 925 parts per thousand by weight of silver and 75 parts per thousand of copper. Plantsurfer (talk) 15:47, 1 August 2008 (UTC)

We should link "sterling silver" to http://en.wikipedia.org/wiki/Sterling_silver Wrnchhead76 (talk) 16:40, 14 October 2009 (UTC)wrnchhead76

It's already linked. Do a search for "sterling silver"; the second occurrence is linked.—Tetracube (talk) 16:58, 14 October 2009 (UTC)

S.A.W.

I noticed that under History the abbreviation S.A.W. appears after Muhammed's name. I know that this is common practice in Islam, but I can't imagine it's considered good form here. Unless there's an editing guideline to support this, I'm of the opinion it should be removed. A10t2 (talk) 15:42, 1 August 2008 (UTC)

Silver as food additive banned in Australia

This article mentions (without citation) that silver is banned in Australia as a food additive. Although this seems to pop up everywhere when searching on Google, upon checking the Australian Food Standards website it seems that this is either just a rumour, or that it was once banned in Australia and that this has since changed.

Either way, if you go to http://www.foodstandards.gov.au/thecode/foodstandardscode.cfm and check Part 1.3.1 Schedule 1, it looks to be legal, as long as it doesn't exceed the level stated by the Good Manufacturing Practice. I didn't actually look into the Good Manufacturing Practice, but nonetheless it seems as if it's legal.

Or I'm just looking at the wrong thing altogether in a misguided search for righteousness. That sounds about right.

Silver drematicly decling in photography?

Silversmithery

This section is oversize for this article, and should be rigorously condensed. There is a main article silversmith, and therefore this article only needs a brief, generalized statement about it. At present the section is loosely written, straying into areas of European history that have no direct relevance to silver,(viz. most of the second paragraph). It also deals with European silversmithing in a way that gives an unbalanced picture. The section scarcely deals with other areas of world silversmithing. This section needs to be a crisp statement of the pivotal developments in the history of world silversmithery since antiquity, that provides overview, not the names and specific products of individual European silversmiths. Those details should be developed in another article. Plantsurfer (talk) 11:12, 1 March 2009 (UTC)

As you say, this section is covering the same material as silversmith (which is a redirect of silversmithery). The content of the section here beeds to be merged into that article, and only a summary left here. This will mean that the material added here, which looks interesting, will not be lost. This is an article on silver as a chemical element: it ought not to have much detail on any particular aspect, something to be left to sub-articles. I would suggest that the section title should become "silverware". It will be necessary to defend the summary against those who would seek to expand it expand it again. I thought that silverware was going to be a further duplicate, but it turns out to be a disambiguation page. Nevertheless, that might be the best location for the merged page, the disambiguation being dealt with in a capnote. Peterkingiron (talk) 10:19, 2 March 2009 (UTC)

I have moved the section to be a subsection of Precious metal. I will use the information when I rewrite the Silversmith article soon and then clean up the section here. Bryancpark (talk) 22:20, 27 July 2009 (UTC)

Silver and money

"The words for "silver" and "money" are the same in at least 14 languages." seems suspicious. Not in most East and West-European languages (except for French), not in Japanese, Chinese and Korean. Any idea? Materialscientist (talk) 03:10, 21 August 2009 (UTC)

Surely the answer is obvious. Coinage was largely made of silver bullion. In UK, we had gold, silver, and copper coinage so that the use of a different word is not surprising. However, the coinage was ultimately based: a pound (money) in English medieval Latin liber sterlingorum, which could be roughly translated as a pound (presumably weight) of sterling (silver). English currency effectively went from a silver standard to the gold standard in the 18th century, when the value of the (gold) guinea, which had previoualy fluctuated was fixed at 21 shillings. Peterkingiron (talk) 16:19, 22 August 2009 (UTC)

Sorry, I miss the answer on in which active 14 languages silver and money are same word. Obsolete terms wouldn't count here. Materialscientist (talk) 23:40, 22 August 2009 (UTC)

Use in horticulture

This is a section copied from the Colloidal silver article. I feel since it was removed there, it should go on here as it a well referenced paragraph that at the very least applies to something silvery.

Originally posted by User:Stmrlbs on June 16th, 2009, 22:33 [1]:

Silver ions have been shown to be an ethylene inhibitor by competing with ethylene for binding sites by the plant receptors. Because of this property, solutions containing silver ions are sometimes used by florist to keep flowers fresh longer . Since ethylene is also involved in the "sexing" of plants, this property of blocking ethylene synthesis is also used for forcing male flowers on female plants. As a result, the use of colloidal silver has become popular in Cannabis cultivation.

Article update

Found this list in the Peer Review backlog and went through the lists. By the time I commented on the two talks pages after the article copyedit, forgot to comment here - apologies for that. Reworded throughout for clarification, attempted to make some statements more neutral, did the ## units thing and later standardized abbreviations. The applications section is rearranged - a number of one/two sentence sub-sections consolidated into 'Other industrial and commercial uses'; 'Medical' and 'Medicine' merged into 'Medicinal'; and redundant commentary minimized.--MornMore (talk) 09:54, 12 November 2009 (UTC)

- Oddly no mention is made of the Potosí mine in modern Bolivia. It was this mine that supplied the Spanish treasure fleets. Because prior to independence Bolivia and Peru were regarded as one territory, we have the slightly misleading assertion that it was Peru (not Bolivia)that has been a major source of silver since the 16th century. The fact that Wikipedia itself has several articles referring to places named after Potosí is indicative of the legendary vastness of the lode Everybody got to be somewhere!

- Missing history of silver in China. China's economy was based on silver even into the 20th century and partially protected the country form the Great Depression (why I don't know). How much silver circulated in China? Did it rival Roma during any dynasty? How much did China have during Han Dynasty when Roma existed? Did first banks in China start with silver? The noun bank is 银行 (silver shop). Much of American silver went to China, trade deficits, so much that this event help motive UK to sell opium in China to balance trade (even though opium was illegal in UK).

Silver as a conductor in cables for high quality audio

The silver article contains a mention of using silver for special high quality audio and power connector cables. This is pure quackery. I have tried to remove it twice but it has been immediately reinstated by Markvs88 without any reason or explanation, despite my invitation to discuss it here. At the very least such outrageously unscientific points of view should be introduced by words such as "some schools of thought believe ..." 90.214.249.180 (talk) 23:47, 29 November 2010 (UTC)

I agree thoroughly. Silver is widely used in radio frequency applications where the skin effect really does make the higher conductivity marginally useful. The fact that the tarnish on silver is also a good conductor increases its attraction to RF designers for mating surfaces of connectors. The difference in conductivity between copper (16.78 nΩ·m) and silver (15.87 nΩ·m) is less than 6%. Audiophools can get exactly the same effect by increasing the size of conductors by that amount! RF engineers are constrained in the dimensions they can use by the nature of tuned circuits and so cannot do this. They therefore do use silver as a conductor. Audiophools discovered that the military used silver (plated) conductors in their 'cost no object' radio equipment and considered that this inevitably had a benefit for them. This is not the case. — Preceding unsigned comment added by Andy.Cowley (talk • contribs) 02:18, 5 February 2011 (UTC)

Yes, I've reverted it twice. Your invitation to chat was actually a call to see if "I could get support" to keep in something you wanted to remove, which doesn't make a whole lot of sense -- by that logic you could delete about a third of the article (nevermind a whole lot of Wikipedia). I also don't find "rubbish" and "techno-babble" to be very descriptive. However, if you would explain why the points should be deleted, I'm open to read it. Best, Markvs88 (talk) 02:48, 30 November 2010 (UTC)

Err. I was hoping you could say something factual about this application and spare my time from looking it up from scratch. Unfortunately I can't access the quoted ref, at least now. Materialscientist (talk) 02:58, 30 November 2010 (UTC)

There is a small group of manufacturers exploiting a niche market where they have convinced audio enthusiasts that copper wire is not good enough for connecting things together, and that silver is better. And of course their products aimed at this market are outrageously expensive, affordable only by those who have more money than sense. The power cable example illustrates the total absence of scientific reasoning behind this kind of product: why would using one meter of silver power cable between the wall socket and your amplifier make it sound different or better? The remaining 99.99% of the power delivery circuit back through the switchboard to the electricity utility's distribution system is made of copper! Wikipedia should not condone or permit any attempts by interested parties to promote (however discretely) these silver-based wiring products. 90.214.249.180 (talk) 12:57, 30 November 2010 (UTC)

While I understand your desire to right a percieved wrong/untruth (and your considerable knowledge in this field), Wikipedia isn't in search of truth, but wp:verifiability. Consider the line: "Some high-end audio hardware (DACs, preamplifiers, etc.) are fully silver-wired, which is believed to cause the least loss of quality in the signal." It's pretty neutral in tone. It doesn't state categorically that it does the job better nor that the addition of silver makes the sound necessarily better -- just that it is the least loss of signal quality. Is the delta in loss 10% or 0.0001%? I don't know, but the line says that some high-end products use silver. Can you cite either that there are no silver-using "high end audio hardware producers", or perhaps that silver does not have less signal loss than copper? Best, Markvs88 (talk) 14:52, 30 November 2010 (UTC)

Wires used for supplying signals at low voltages don't cause any loss in signal quality, regardless of which metal they are made of. They might collect interference but that will be the same for all metals. Wires for supplying current to heavy loads such as loudspeakers should have the lowest resistance possible - silver wires have a resistance of about 6% less than copper ones of the same size, but cost 800 times as much. Not a very good engineering solution: a better idea would be to use 6% more copper, which will reduce the resistance to the value for the silver wires, and yet only cost 6% more! Based on resistivity of Ag = 1.59×10−8 Ω·m, Cu = 1.68×10−8 Ω·m, price of Ag = $25/troy oz, Cu = $8.50/kg, 1kg = 32 troy oz. I repeat: the marketing of silver wires is a ploy to extract cash from people with more money than sense. 90.214.249.180 (talk) 21:55, 30 November 2010 (UTC)

Sure, but there are two separate issues here - (i) whether silver is needed there (most likely not, even for low-Ohm speakers) (ii) whether it is actually used there (for marketing purposes), like it or not. Materialscientist (talk) 22:55, 30 November 2010 (UTC)

90.214.249.180, you're debating cost vs. performance but you've just admitted that silver has a (minimally) lower resistance than copper. I can't see any reason for the removal of the point given its tone. If you like, I would support you adding (preferably with a citation) as to why this claim is spurious per your posting here, but not its removal as it is basically factual. Best, Markvs88 (talk) 23:53, 30 November 2010 (UTC)

PS: Just thought of the clincher argument ... bullets are made of lead, because bullets are supposed to be heavy, and lead is a dense metal. But gold is even denser, so why not make bullets out of gold? Reason: gold bullets are admittedly good, but too expensive; if you want heavier bullets, make bigger ones using lead! 90.214.249.180 (talk) 23:46, 30 November 2010 (UTC)

Argentum root

In the article, which of the two following statements is correct? The Intro says Latin: argentum, from the Indo-European root *arg- for "grey" or "shining", while the History section says from the Indo-European root *arg- meaning "white" or "shining". I suspect grey is wrong, because grey doesn't shine, but I equally suspect silver isn't white! Does anyone know a printed source for the Indo-European root of *arg, to clear this up?

Silver notation as "AR"

There is a symbol for silver not mentioned in the article. "AR" is used to denote silver in numismatic circles. In these scenarios Ag is only really used when the coin is worn such that it is only worth the silver bullion value. I am not going to add this as it is frustratingly hard to reference (and from experience, unreferenced inclusions get deleted)! If you type AR coin into google though all the images are silver coins... but i can't find it written.  :/ 90.193.233.49 (talk) 11:10, 22 September 2012 (UTC)

Even if proper sources were found documenting such, the terms are extraneous to the subject of silver, and best not included in this article. The most common standardized abbreviation and brief etymology is given and sufficient. The term "AR" as related to describing silver coins of antiquity is more related to the subjects of numismatics or coin grading or AR, et al. Ah, the last does have an entry for AR being "Argent, the heraldic tincture of silver". -- EsotericRogue Talk 09:12, 21 October 2012 (UTC)

Electron configuration

My humblest apologies, but I could not find the appropriate place to put this question, but why is the noble gas abbreviation given as the electron configuration, and it doesn't look correct? Should it not be [Kr] 5s^2 4d^9? I'm currently teaching electron configuration and noble gas abbreviations to my students, and would love an explanation if I'm mistaken. 68.207.188.211 (talk) 02:33, 31 October 2012 (UTC)Wynni/Wynnifitz

The "usual" explanation is that half- and fully-filled orbitals are preferable in general, thus 5s2 4d9 is higher in energy than 5s1 4d10. This is similar to copper's electron configuration of 3d10 4s1. The usual counterexample is the electron configurations of Ni, Pd, Pt: [Ar]3d8 4s2, [Kr]4d10, [Xe]4f14 5d9 6s1.

I don't know the answer off the top of my head, but I believe spin orbit coupling and relativistic effects are invoked for the heavier metals. --Rifleman 82 (talk) 15:17, 31 October 2012 (UTC)

For Cu, Ag, and Au, the stability of a filled d-subshell gives them a ground state nd¹⁰(n+1)s¹ configuration, with nd⁹(n+1)s² being the first excited state. However, for Au, relativistic effects must be taken into account and the s electrons are also relativistically stabilized; this effect is even larger for Rg, where the 6d⁹7s² configuration is so stabilized that it becomes the ground state. (This can be seen in group 6 too: for Cr and Mo, the stability of a half-filled d-subshell appears to dominate, giving a nd⁵(n+1)s¹ configuration, but for W and Sg, where relativistic effects need to be taken into account, the stabilization of a filled s-subshell appears to dominate, giving a nd⁴(n+1)s² configuration.)

There was no market manipulation in 1980. Silver was up because dollar temporary lost its reserve currency status. There are 1.2 million tones of silver above ground. How could Hunt brothers corner it by buying only 3,000 tones of silver? Warren Buffet bought 200,000,000 ounces of silver in 1997 (2 times more than Hunt brothers) but price of silver didn't change.

The Hunt brothers bought futures contracts above and beyond their physical purchases, this is called leverage, as the price rose the value of their contracts rose and they parlayed that into more contracts, until the exchange and the FED stepped in and forced the price back down. — Preceding unsigned comment added by 208.74.131.178 (talk) 06:23, 16 August 2011 (UTC)

Silver as a Food additive in the USA (Use in food)

Regarding the closing [citation needed]

A quick well-tailored google search pulled up a document from the FDA which stated that a silver nitrate and hydrogen peroxide solution is approved for use in bottled water as an antimicrobial (obviously in minute quantities). The only other FDA-approved use I could find anywhere was for it's use in cosmetics as a coloring (fingernail polish, not exceeding 1%).

It's all Greek and Roll to me

I'm all for the inclusion of information but (a) people who are curious for the Greek translation of silver can go to Wiktionary or click the Greek link in the left column already; (b) we only list relevant foreign names in English articles and the modern Greek word and its modern Greek transliteration certainly don't count; (c) even the ancient Greek form—where upsilon is transliterated y—is entirely beside the point: the symbol Ag came from its Latin name and only its Latin name. We need to keep WP:LEAD sections terse and informative, especially the WP:FIRSTSENTENCE. The PIE (≠"Indo-European") is already probably too much but is at least slightly informative as to where the Latin name came from. — LlywelynII 07:33, 8 February 2016 (UTC)

Question

“Reaching a peak production of 200 t per year, an estimated silver stock of 10,000 t circulated in the Roman economy in the middle of the second century AD, five to ten times larger than the combined amount of silver available to medieval Europe and the Caliphate around 800 AD.” So, most of that silver ended up in China, right? Is there a source to trace the destiny of all this silver? Eight or nine kilotons of silver travelled through the Silk Route by those six centuries? Just this is a very curious question, and I don't believe that a large portion of that silver could just be lost or transformed. I think that the answer, is available, should be put into the article beside the quote. Thanks. - 91.122.6.219 (talk) 19:31, 11 June 2016 (UTC)

Jclemens' Good Article Review expectations for Vital Articles.

• This is a vital article. As such, it requires an appropriate amount of scrutiny, because being wrong is just that much worse, so being right is just that much more important.
• This is a collaborative process. I offer suggestions, which editors are free to implement, ignore, reject, or propose counter-suggestions. If there's simply no meeting of the minds, there will be no GA pass from me, but please feel free to tell me to take a flying leap if I propose something stupid or counterproductive.
• I do not quick fail vital article GA reviews. In general, even if there is no clear path to meet all the GA criteria, working with conscientious editors is almost always going to improve the article and benefit our readers--just not to the extent all of us had hoped.
• This is not a quick process. Estimate a month, depending on my availability and the responsiveness of the nominator and other editors collaborating on the process.
• I am not a content expert. I generally have a reasonable background in the topic under consideration, often at the college undergraduate/survey level, or else I wouldn't have volunteered to review it. Thus, I depend on the content experts to help focus the article appropriately.
• The more the merrier. While many unimportant GA articles can be adequately reviewed by a single nominator and a single reviewer, Vital Article GA's can use more eyes, based on their increased importance. I always welcome other editors to jump in with suggestions and constructive criticisms.

Initial read-through

Lead

• "Silver metal is used in many premodern monetary systems" is? was? It's surely still used in coinage somewhere, but I wouldn't call those pre-modern systems.
  • Pure silver metal, to my knowledge, is basically a premodern thing outside special bullion coins; I would agree that silver alloys shouldn't be called a "premodern" use because they were in use till quite recently, though I don't think there are any left now. Anyway I think this is probably too much detail for the lede, so I've cut it to just say that Ag is used in bullion coins (it's one of those four metals to have a currency code, along with Au, Pt, and Pd). Double sharp (talk) 15:26, 4 May 2017 (UTC)
• "Silver is used in numerous applications other than currency, such as solar panels, water filtration, jewellery, ornaments, high-value tableware and utensils (hence the term silverware), and as an investment medium (coins and bullion)." Of all of these, water filtration is not a specific item, while everything else in this list is. That may be OK, but do you want to tighten that up? Jclemens (talk) 05:43, 2 May 2017 (UTC)

Occurrence and production

• How do the first sentences of the first and third paragraphs related to each other? They seen redundant, describing silver's combination with sulfur in nature.
• Compared to what Iron had, there doesn't appear to be a lot about the process of production. Jclemens (talk) 02:55, 3 May 2017 (UTC)
  • What I was going for here is that the first paragraph describes minerals containing primarily Ag; but these are too sparse now to serve as useful sources, so the rest of the section describes instead the current sources, which have Ag as a secondary constituent. Because true silver ores are not really exploited today (too little of that) there is naturally not as much about production as there is for Fe. Most of the Ag produced from ores of base metals like Cu, Pb, and Zn follows the production of those metals until the electrolytic steps covered in the article (which uses Cu as the example), so the stuff before that isn't really focused on Ag and varies quite widely depending on which metal is being followed. I will try to tighten this to make it clearer, hopefully by tomorrow. Double sharp (talk) 15:10, 3 May 2017 (UTC)

• For the urinary catheter and VAP references, I'd recommend putting them with their specific clauses, rather than together at the end of the paragraph, even though it's quite clear by title which refers to which.
• Is anyone actually still making vacuum tubes? The tense implies so.
  • Yes, but mostly for restoration of vintage equipment. Since this is essentially a historical application now I've changed the tense for it. Double sharp (talk) 15:32, 4 May 2017 (UTC)

  • Yeah, I wondered about that for a while. The trouble I find is that both sections feel slightly incomplete without the explosive notes: like it or not, explosion is kind of the signature reaction of these compounds (the silver azide article has the hilarious line "In its most characteristic reaction, the solid decomposes explosively"), and it is quite evidently something that one needs to be wary of. For that reason I rather like the near-duplication, since the first mention focuses on the chemistry of what happens, and the mention in "Precautions" focuses on how to stop it from happening in the first place. ^_^ Double sharp (talk) 15:47, 4 May 2017 (UTC)

Silver

Where did the word come from??? — Preceding unsigned comment added by 210.23.80.173 (talk) 22:19, 11 April 2013 (UTC)

There is something about the Latin and Greek words for silver in the article, but very little about the Teutonic word "silver". I think you will find that it appears in all Teutonic languages with regular sound laws. It seems to be unrelated to the above two mentioned. — Preceding unsigned comment added by MissouriOzark1947 (talk • contribs) 11:52, 22 September 2014 (UTC)

This is a very old borrowing of unknown provenance, possibly Akkadian sarpu. It is not only the source of all the Germanic words for Ag, but also the Slavic ones (e.g. Polish srebro, Russian серебро). Double sharp (talk) 08:24, 8 August 2016 (UTC)

why's this edit being deleted?

Silver nano particles have been shown to react with stomach acid producing the toxic salt silver chloride. Silver has been shown to negatively effect glutathione in mammals.

Well, for starters, because people not signing their posts and using references on talk pages are disliked in general. The misuse of "effect" probably also has something to do with it. — LlywelynII 07:34, 8 February 2016 (UTC)

Silver as synonym for money

Apologies if I have missed this, but is it not worthy of mention in the article that in some languages the word for "silver" is actually used as the term for money itself (e.g., French, "de l'argent"), much as in other languages, the term for "gold" (with slight modifications) is used as the term for money (e.g., German "gelt")?--Partnerfrance (talk) 12:17, 12 March 2019 (UTC)

Units for density?

I came here looking for the density of silver. Does it really make sense to list it as g/cm³?

I get that it is equivalent to kg/dm³ (i.e. kg/l) and t/m³ (1000 kg/m³) and mg/mm³, but those units have a better divisors for calculations (except for maybe kg/dm³, which then again is very useful for liquids). Even though cm³ is a very relatable size because cm is very practical in normal, day-to-day usage, cm is still a bit of an in-between unit and can be a bit unwealdy for calculations because of the exponent -2 in its prefix, making mm³ slightly better (though also less relatable) in this regard. Would it make sense for the infobox to also list the densities as 1000 kg/m³ (or t/m³), kg/dm³ (kg/l) and/or mg/mm³? — 84.248.218.89 (talk) 08:14, 7 May 2019 (UTC)

Reference 91 feels like a link to sell and is not informative

Inline as of this writing, the article reads "In 2015 China reverted to the metric system and currently prices silver (and gold) in grams.[91][92]" -- reference 92 links to a legitimate source of information about this topic, however reference 91 is a link to a silver seller website with no value (and it's selling a lot of silver in troy ounces, which is rather the opposite of the point trying to be made).

1. In the introduction, "silverware" ought to be placed in quotation marks, since the article is talking about the word itself, not merely the things to which the word refers.
2. bullet cast from silver should be changed to bullet cast from silver, since "silver bullet" is more relevant to this passage than merely "bullet" is.

Semi-protected edit request on 20 November 2020 - Silver in the Marine Environment

Silver in the Marine Environment

In seawater, the concentration of silver is quite low (pmol/L). Levels vary amongst different depths and between water bodies. Dissolved silver concentrations range from 0.3 pmol/L to 22.8 pmol/L, in coastal surface waters and pelagic deep waters, respectfully. Analyzing the presence and dynamics of silver in marine environments is difficult due to these particularly low concentrations and complex interactions in the environment. Although a rare trace metal, sources from fluvial, aeolian, atmospheric, and upwelling inputs, as well as anthropogenic inputs via discharge, waste disposal, and emissions from industrial companies greatly impact concentrations. Other internal processes such as decomposition of organic matter may be a source of dissolved silver in deeper waters, which feeds into some surface waters through upwelling and vertical mixing.

A nutrient-like vertical profile in the Atlantic and Pacific demonstrate minimal surface concentrations, but supplementation in deeper waters. Silver is taken up by plankton in the photic zone, remobilized with depth, and enriched in deep waters. In the Atlantic, this element is then conservatively transported to the other oceanic water masses. In North Pacific waters, silver remains a nutrient-type profile, but is remobilized at a slower rate and increasingly enriched compared to deep Atlantic waters. Silver has increasing concentrations that follow the major oceanic conveyor belt that cycles water and nutrients from the North Atlantic to the South Atlantic to the North Pacific.

There is not an extensive amount of data focused on how marine life is affected by silver despite the likely deleterious effects it could have on organisms through bioaccumulation, association with particulate matters, and sorption. It wasn’t until about 1984 when scientists started understanding the chemical characteristics of silver and the toxicity effects that potentially occur when increased concentrations are present. In fact, mercury is the only other trace metal that surpasses the toxic effects of silver; however, the full extent of toxicity of silver is not expected in oceanic conditions because of its ability to transfer into nonreactive biological compounds.

In one study, the presence of excess ionic silver and silver nanoparticles caused bioaccumulation effects on zebrafish organs and altered the chemical pathways within their gills. In addition, there are very early experimental studies that demonstrated how the toxic effects of silver fluctuate with salinity and other parameters, as well as between life stages and different species such as finfish, mollusks, and crustaceans. Finally, another study found raised concentrations of silver in the muscles and liver of cetaceans indicating pollution of this metal within recent decades. Silver is overall not an easy metal for an organism to eliminate and elevated concentrations can unfortunately result in fatality.

I would like to submit a request to add the additional information below regarding Silver found in the ocean under the occurrence section.

Differences in Ag sediments found in the ocean are possibly related to the biogenic and/or scavenged flux to the sediment. Since Ag and Ba are similar, observations conclude that Ag may be supplemented with decaying organic particles as they settle in the ocean, (McKay et. al., 2008). In the Pacific Ocean, Ag concentration and dissolved silicic acid concentration are strongly related. However, Ag is exhausted at medium depths where there is low concentrations of dissolved O2, suggesting Ag is removed from oxygen-depleted waters by scavenging and/or precipitation, (Kramer et. al., 2011). Several vertical profiles confirm that silver is distributed within the water column as a nutrient‐type element and is more noticeable in the Pacific than it is in the Atlantic. Silver was again associated with dissolved silica, but fluctuated between the Pacific and the Atlantic oceans, implying that silver is slower to remobilize in the deep Pacific than in the deep Atlantic or refractory silver is being advected from the Atlantic to the Pacific. Additionally, silver was also positively, but inconsistently, linked with copper, confirming that Ag:Cu ratios can be used as geochemical tracer of water masses. Silver concentrations in the ocean were up to 12 pM in surface waters and were the highest measured in the ocean, in intermediate waters (2400–2500 m) silver measurements were (e.g., 88 pM) were estimated to be four‐fold greater than (e.g., 23 pM) previously measured in eastern North Pacific waters [Martin et al., 1983]. This increase in silver concentrations in the North Pacific is tentatively credited to the increase in Asian industrial emissions and their absorption into the water column. It is proposed those discharges have increased levels in silver in surface waters as much as 50‐fold above theoretical background values. If confirmed, this development proves that a large anthropogenic perturbation of the ocean biogeochemical cycling of silver is occurring, and that silver is one of the most (if not the most) polluted elements in the World Ocean, (Ranville, 2005). Vertical profiles of total dissolved silver concentrations in the equatorial and southwest Atlantic Ocean provide a different perspective on the processes influencing the element's external fluxes and internal biogeochemical cycling in the ocean. Natural and/or industrial aerosols from the atmosphere appear to raise silver concentrations in South Atlantic surface waters, where silver is scavenged onto and/or bioaccumulated by plankton. The remobilization of silver with depth is comparative with silicate, indicating much of that silver is separated within a refractory organic phase correlated with biogenic silica. Silver is then remineralized, and then carried in subsurface water quantities throughout the ocean, (Ndung’u et. al., 2001).

Silver is a recycled element with low concentrations in surface waters and high concentrations in deep waters (4600 m) of the Atlantic, which is a systematic enrichment of silver in deep waters from the North Atlantic to the North Pacific. This nutrient-type distribution is also demonstrated by the highly significant (p < 0.01, simple linear regression) correlation (R ≥ 0.916) of silver and silicate concentrations in both the North Pacific and eastern Atlantic, (Flegal, 1995).

History Section: Use of silver as "primitive money"

The History section of this article makes the following claim:

"In particular, the three metals of group 11, copper, silver, and gold, occur in the elemental form in nature and were probably used as the first primitive forms of money as opposed to simple bartering."

The supporting citation is a passage from Greenwood and Earnshaw, Chemistry of the elements which states:

"Collectively known as the 'coinage metals' because of their former usage, these elements were almost certainly the first three metals known to man. All of them occur in the elemental, or 'native', form and must have been used as primitive money long before the introduction of gold coins in Egypt around 3400 BC."

The claim that these metals "must have been used as primitive money" is vague and largely unsubstantiated in both the article and the citation. It seems to suggest that silver's primary use to most prehistoric cultures was monetary, stemming from the fact that it "occur[s] in the elemental form in nature." However there isn't enough evidence provided to support this. Also of issue is the framing of "primitive forms of money" as something "opposed to simple bartering," a position that I did not find mentioned in the cited source.

The article goes on to state that "silver did not lead to the growth of metallurgy on account of its low structural strength, and was more often used ornamentally or as money." While the source cited in this passage does make several mentions of silver's low structural strength and ornamental use, it does not refer to any prehistoric cultures using silver as a form of currency.

Perhaps this portion of the article should be re-written to remove the claim in question. Additional citations may be needed to summarize the significance of silver to prehistoric cultures as a form of currency. However, the issue seems primarily theoretical and I question the relevance to this particular article. It might be helpful to link to another article that discusses "primitive money" more specifically, such as History of money, further down under the "Monetary use" section.

Admittedly this is a lot of attention to give such a relatively small detail, but it stood out to me as requiring at least some discussion or consideration given it's prominent placement at the beginning of the History section. Apologies if I've overlooked any standard practices, I'm relatively new to contributing.

There is a photo about halfway through the article of various silver plates/platters, goblets/tankards and other serving bowl-type items, presumably to illustrate the idea of "silverware". Given that there are no actual eating implements of any kind in this picture, can the objects pictured accurately be labeled as "cutlery"?
