Bond Polarity and Electronegativity The electron pairs shared between two atoms are not necessarily shared equally Extreme examples: 1. In Cl 2 the shared electron pairs is shared equally 2. In NaCl the 3 s electron is stripped from the Na atom and is incorporated into the electronic structure of the Cl atom - and the compound is most accurately described as consisting of individual Na + and Cl - ions For most covalent substances, their bond character falls between these two extremes Bond polarity is a useful concept for describing the sharing of electrons between atoms A nonpolar covalent bond is one in which the electrons are shared equally between two atoms A polar covalent bond is one in which one atom has a greater attraction for the electrons than the other atom . If this relative attraction is great enough, then the bond is an ionic bond Electronegativity A quantity termed 'electronegativity' is used to determine whether a given bond will be nonpolar covalent , polar covalent
