Polyatomic ions are atoms held together by covalent bonds as a group and that from CHM 1220 at Wayne State University
Ions in ionic compounds are primarily held together by the electrostatic forces between the charge distribution of these bodies, and in particular the ionic bond resulting from the long-ranged Coulomb attraction between the net charge on anions and cations.
