Ionocovalency has Natural Values

The IC has an absolute potential values [1]. It has same values range as that of its atomic core charge. This phenomenon is particularly noticeable for the top period elements which have not yet experienced much shielding effects. The atomic core charge is an effective nuclear charge and is always markedly less than the actual nuclear charge Z, but, as the shielding is not perfect, the core charge increases as Z increases, but more slowly. In IC-model, the effective nuclear change is determined by natural IE, not from the calculation by Slater shielding constants as that of the Allred-Rochow electronegativity XAR [2].
