Is an ion a molecule?

While the IUPAC defines "molecule" as "an electrically neutral entity consisting of more than one atom (n > 1)", the term is used in chemistry in a much looser sense. Google "ion is a molecule" (with quotes) and you will find plenty of "authoritative" places that say "an ion is a molecule with charge". That is, for many chemists, the concept of molecule includes ions.
As a mathematician, I fervently believe that zero is a perfectly legitimate number, with all the rights and privileges pertaining thereto. So I am siding with the chemists on this one: a neutral molecule is obviously just a zerovalent ion.
Also, you will find that many chemists and physicists would not blink or sneer on hearing "monoatomic molecule". And, again as a mathematician, I find that excluding n = 1 is sillines that borders on the sacrilegical.
All the best, --Jorge Stolfi (talk) 19:39, 27 April 2019 (UTC)[reply]
