The melting-points, interatomic distances and compressibilities of the transition elements are reviewed, and are shown not to be in complete agreement with the valency scheme proposed by Pauling. In all three Long Periods on passing from Groups I A to IV A there is a steady rise in melting-point, and decrease in interatomic distance and compressibility, and for these elements Pauling’s view of a metallic valency equal to the Group number is correct. In the First Long Period there is…
