Specifics[edit]

If the category is retained, we should discuss what should remain in it.... (I think this discussion should be here, regardless of the CfD discussion I initiated.)

mononeutron probably qualifies as an isotope.
dineutron and tetraneutron may not qualify as isotopes; isn't there a requirement that the thing stay around long enough to be measured? I guess not. We have Beryllium-8, which is about as stable as the dineutron.
trineutron and pentaneutron almost certainly do not qualify as isotopes; the comment on them in neutronium says that they are names for things which do not exist.

Also, shouldn't the names placed in this category match those of isotopes of elements; hence

Neutronium-1 (redirect to neutron?)
Neutronium-2 (redirect to dineutron, if not merged)
Neutronium-3 (if present, redirect to Neutronium#Neutronium and the periodic table, which probably should be Neutronium#Isotopes or isotopes of neutronium)
Neutronium-4 (redirect to tetraneutron), if not merged)
Neutronium-5 (if present, redirect as Neutronium-3).
