The symbol for the oxyanion perchlorate ion is ClO4-.
The oxyanion of chlorine that contains the most oxygen atoms is perchlorate (ClO4-).
Chlorite Ion
Chlorate ion
This anion is called metavanadate.

No, the name of an oxyanion is not based on the amount of a metal in the ion. The name of an oxyanion is determined by the oxidation state of the element and the number of oxygen atoms in the ion. The metal in the ion may play a role in determining the charge or oxidation state of the element, but it does not directly determine the name of the oxyanion.
No, ammonium is not an oxyanion. It is a polyatomic cation composed of one nitrogen atom and four hydrogen atoms, with a net positive charge. Oxyanions are negatively charged ions that contain oxygen.
A xenate is an oxyanion of xenon, chemical formula HXeO4.
The oxyanion of the acid HC2H3O2(aq) is acetate ion (C2H3O2^-).
