On the electrical conductivity of transition metals
  We study the consequences of identifying the 'electron density parameter' N of Miedema et al. as the accurate valence of metallic elements. The incorporation of these as valence in Pauling's scheme for the electronic structure of transition metals, predicts, for the first time, that the electrical conductivity of transition metals would decrease in the order {\sigma}_Ag > {\sigma}_Cu > {\sigma}_Au > {\sigma}_Rh > {\sigma}_others, as is experimentally observed.
