Polyatomic ions are atoms held together by covalent bonds as a group and that from CHM 1220 at Wayne State University
A polyatomic ionic compound is a compound made up of a polyatomic ion, which is two or more atoms bonded together, and a metal. Naming polyatomic ions is harder, but doable. First, name the cation, which is just the name of the element. Next, name the anion.
