The Bulk Electron Concentration (BEC), the number of net-bonding valence electrons per unit volume in cm³, n_e, of 59 solid substances are correlated with the bulk moduli of elasticity, B, for the elements of each Group of the Periodic Table separately on linear scale. All those elements except transition metals from Group IVA (Ti) through Group IB (Cu) there exists linear B-n_e relations. For those transition metals there, however, exists symmetrical B-n_e behaviors toward the Mn and Fe group metals respectively from those Ti and Cu groups. From the correlations the Average Valence Bond Strengths (AVBS) per electron of those 59 substances are derived. It is demonstrated from the correlations that the free electron theory of metals does not applicable to none of the elements in the Periodic Table, however, it would nearly applicable to the most simple Alkali Metals provided that the effective electron mass m^* is appropriately assigned to each element of these metals. The empirical effective masses are calculated from the correlations.
