A molecule may be nonpolar either when there is an equal sharing of electrons between the two atoms of a diatomic molecule or because of the symmetrical arrangement of polar bonds in a more complex molecule. Nonpolar covalent bonds are bonds where both atoms possess the same electronegativity, and therefore the electrons in the electron bond are shared equally between them.Note that this must occur between two nonmetal atoms in order for it to be a proper nonpolar covalent bond.
