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.

A polyatomic ion, also known as a molecular ion, is a charged chemical species(ion) composed of two or more atoms covalently bonded or of a metal complex that can be considered to be acting as a single unit.

Eg: SO42−, CO32−

Polyatomic ions: Those ions which are formed from groups of joined atoms are called polyatomic ions.
Compound ions are also called polyatomic ions.

For e.g
Ammonium ion NH⁴⁺, is a compound ion which is made up of two types of atoms joined together nitrogen and hydrogen.

Carbonate ion CO3²- , is a compound ions which is made up of two types of atoms joined together carbon and oxygen.

Similarly , sulphate ion SO4²-, Nitrate ion NO3^- , hydroxide ion OH^- e.t.c
