Polyatomic Ion

As we move further in Chemistry class we know polyatomic ions are very important.A polyatomic ion, also known as a molecular ion, is a charged opns composed of two or more atoms covalently bonded or of a metal complex that can be considered as acting as a single unit in the context of acid and base chemistry or in the formation of salts. The prefix poly- means many in Greek, but even ions of two atoms are commonly referred to as polyatomic. In older literature, a polyatomic ion is also referred to as a radical, and less commonly, as a radical group.
