| − | A '''polar covalent bond''' is a [[covalent bond]] in which the shared [[electron]]s are shared unequally between the two bonded atoms. A purely covalent bond results in the [[molecule]] having an electrical charge. | + | A '''polar covalent bond''' is a [[covalent bond]] in which the shared [[electron]]s are shared unequally between the two bonded [[atom]]s. This results in a [[charge]] difference across the bond, though it does not change the charge of the whole [[molecule]]. |
