Polyatomic ions are charged molecules . The atoms within a polyatomic ion are usually very tightly bound together, so the ion retains its identity within ionic compounds and over the course of many chemical reactions.

Polyatomic ions are ions which consist of more than one atom. For example, nitrate ion, NO3-, contains one nitrogen atom and three oxygen atoms. The atoms in a polyatomic ion are usually covalently bonded to one another, and therefore stay together as a single, charged unit.
