Question

What are
polyatomic ions? Give examples.​

Answer 1

Answer:

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.

Answer 2

Answer:

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.
