What is an example of a polyatomic ion?
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. Rule 1.
Is NH4+ a polyatomic ion?
NH4 is the positive polyatomic Ammonium. It is one of the few positive polyatomic ions.
