Talk:Oxyanion

Merge notice
There are two stubs, oxyanion and oxoanions, covering the same subject, though the content is different. A quick Google search shows oxyanions:oxoanions are in the ratio 4:1, and oxyanion:oxoanion are in the ratio 60:1. Therefore I am proposing that oxyanion become the main article, with oxoanion, oxoanions and oxyanions being redirects. One problem is that I note there is a Category:oxoanions, should this be renamed to Category:oxyanions? I don't have strong opinions either way (I've heard both oxy and oxo), is there a name recommended by IUPAC? Whatever we choose, we shouldn't have two parallel articles.

Revision: I checked with our IUPAC expert here, and he tells me that oxoacids is the preferred term for the related acids, and since we also have the category oxoanions, I would like to merge these into one article at oxoanion, with the others being redirects. The norm on Wikipedia is for a topic to be in the singular, while cats are usually plural. Any comments? Walkerma 06:31, 6 February 2006 (UTC)


 * I searched the Pubmed database of medical/biochemical literature and find 24 uses of Oxoanion and 632 uses of Oxyanion. The ISI Web of Science finds 137 for Oxo and 959 for Oxy. Suggest merging and redirecting to Oxyanion and then proposing a category rename as well. Thatcher131 01:58, 13 February 2006 (UTC)

Oxyanion definition
An oxyanion or oxoanion is a chemical compound with the generic formula AxOyz− (where A represents a chemical element and O represents an oxygen atom).

Would water (hydrogen oxide) and hydrogen peroxide be considered oxyanions, because they don't seem to be named as oxyanions. My thought was that the "A" had to represent another substance other than oxygen or hydrogen. 64.107.219.15 (talk) 22:45, 9 June 2011 (UTC)
 * Water is H2O and not negatively charged. It is not an anion and therefore cannot be an oxyanion. I guess the above definition fro oxyanions [AxOy]z− needs to be amended with x,y,z>0. Same for hydrogen peroxide [H2O2]. It's not anion. However the hydroxide anion OH- could well be considered an oxyanions of hydrogen (A=H, x,y,z=1). I don't see any reason to exclude H from being A. But it is afaik unusual to refer to hydroxide anions as oxyanions. Theroetically also the suproxide anion [O2]- and the peroxide anion [O2]2- could be considerd oxyanions, with A=O. But I don't know if that is considered at all. 2A02:1205:C69F:FC20:CABC:C8FF:FEA7:3DAD (talk) 16:21, 16 August 2016 (UTC)

Chlorate
I think the author jumped to conclusions base on the numbers. The two electrons he's referring to are the lone pair. The other five are valence electrons, forming covalent bonds with the oxygen atom, leaving an odd one out (the negative charge) 2600:1700:6801:C10:68C7:4A0B:2425:7003 (talk) 08:10, 3 May 2023 (UTC)
