Polyatomic ions are atoms held together by covalent bonds as a group and that from CHM 1220 at Wayne State University
A polyatomic ion is a group of two or more atoms covalently bonded or metallically bonded together to function as a single ion. An example would be the hydroxide ion, OH - . The oxygen and hydrogen are covalently bonded together, and function as a single anion with a 1- charge.olyatomic Ions are groups of two or more elements that have a charge associated with them as a group. They can in turn then bond to other elements or polyatomic ions to form more complex structures.
