Ionic bonding is the bonding that involves a transfer of electrons.
Bonds that are partly ionic are called polar covalent bonds. Nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal. The result is a bond where the electron pair is displaced toward the more electronegative atom.
