Explanation:

A polyatomic ion is an ion composed of more than one atom. We identify polyatomic ions based on this definition.

Answer:

Polyatomic ions: $\text{PO}_4^{3 -}$, $\text{NH}_4^{+}$, $\text{OH}^{-}$, $\text{CO}_3^{2 -}$
Not Polyatomic ions: $\text{O}^{2 -}$, $\text{Ca}^{2 +}$, $\text{Cl}^{-}$, $\text{Na}^{+}$
