Polyatomic ions are atoms held together by covalent bonds as a group and that from CHM 1220 at Wayne State University
The atoms in chemical compounds are held together by attractive electrostatic interactions known as chemical bonds. Ionic compounds contain positively and negatively charged ions in a ratio that results in an overall charge of zero. The ions are held together in a regular spatial arrangement by electrostatic forces.
