A covalent bond forming H2 (right) where two hydrogen atoms share the two electrons. 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.
Nonpolar bonds mostly exist between atoms of the same element. For example, oxygen contains six electrons in its outer shell. To gain a full outer shell of eight electrons, oxygen atoms form double bonds with other oxygen atoms. Because they are identical atoms, they share the four electrons equally. When atoms of two different elements share electrons, they form polar covalent bonds. In polar covalent bonds, the shared electrons spend more of their time near one atom than the other, resulting in an uneven sharing and a partial charge on both atoms in the bond. Water is an example of a polar covalent bond.
