WebA negatively charged polyatomic ion that has one or more oxygen atoms bonded to another element is known as an oxyanion; for e.g. the sulphate, nitrate, and carbonate ions. A … WebIons are formed when electrons are lost or gained. A single atom that has lost or gained one or more electrons forms a monoatomic ion, meaning an ion formed from one atom. Groups of atoms covalently bonded together that have lost or gained one or more electrons form a polyatomic ion, meaning an ion composed of two or more atoms.
