Answer:

PO4 3-

Step-by-step explanation:

A polyatomic ion is a group of atoms carrying a charge ( positive or negative ).

A polyatomic ion, also known as a molecular ion, is a covalent bonded set of two or more atoms, or of a metal complex, that can be considered to behave as a single unit and that has a net charge that is not zero.

Whereas S2- is not because it is an inorganic ion
