Functional determination of electric resistance of metals

The periodic system is characterized by objectively existing bonds, which permit to determine functionally the electric resistance of rho electropositive, electronegative and transition metals on the basis of the complex criterion E=zJrV. (z - the element atomic number, J - its numerical meaning in the succession within the period, common for all periods, r - the atom radius, V - its ionization energy). The deviations of the calculated meanings rho constitute approximately 50% of the experimental data. The made analysis of the Wiedemann-Franz law from the point of view of the metal electronegativity permitted to find out that the law does not take this property into account
