A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms.These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding. [better source needed] For many molecules, the sharing of electrons allows.
