Polyatomic ions are atoms held together by covalent bonds as a group and that from CHM 1220 at Wayne State University
Covalent bonds are one of the 3 main types of intramolecular forces, along with ionic bonds and metallic bonds. Covalent bonds are the result of atoms sharing their valence electrons. Covalent bonds can be polar or nonpolar, depending on the electronegativies of the atoms involved in the bond.ovalent bonds are one of the 3 main types of intramolecular forces, along with ionic bonds and metallic bonds.
