So much wrong with this.
A would have to be a cation with a +4 charge for AO2 to be a compound. Oxygen atoms ionise to form O2- anions. +4 cations are rare and therefore this is unlikely.
It's more likely that A would be a non-metal forming a covalent compound with 2 oxygen atoms. Carbon (CO2), Sulphur (SO2), Nitrogen (NO2) are all examples of this. It could also form complex (MnO4-).
There's no such thing as a "diatomic element". O2 is a diatomic molecule. An element cannot have multiple atoms.

You're right about the O and its charge, no idea why I was thinking it only had a -1 charge.
Diatomic elements are molecules that specifically use two atoms of the same kind to exist, I believe there are only 7 of them.
As a covalent compound it could never make sense because we'd have to use the word "dioxide".
And let's not get into complex ions, the names of those are 30+ letters long. American Oxygen would never make sense.
