A covalent bond is a bond in which electrons are shared between atoms of elements. A covalent bond can be polar or nonpolar. In a nonpolar covalent bond, the bond is between two identical atoms and the electrons are evenly shared between the atoms.In contrast, in a polar covalent bond, the bond is between two nonidentical atoms and the electrons are unevenly shared between the atoms. The uneven sharing of electrons takes place because of the difference in the electronegativity...
