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.
AN attempt 1 to resolve misunderstandings regarding ionic-covalent bonding in solids has been. which each contribute one electron to a two-electron bond, and cannot be applied as it stands to ‘dative bond’ systems (such as are found in the zinc.

‘pi’ bonds. When a sigma bond is formed by direct orbital overlap and this brings two parallel ‘p’ orbitals into close proximity then these can overlap sideways (laterally) to form a region of electron density that is not directly between the two nuclear centres but which nevertheless contributes to bonding.
