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

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)[reply]

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)[reply]

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)[reply]
