摘要: The paramagnetic susceptibility X of some the transition elements in temperature range 20 to 1800 °C has been measured. values at 10 -6 e. m. u. /g are: Ti, 3.36; Zr, 1.33; Hf, 0.38; V, 5.64; Nb, 2.3; Ta, 0.85; Mo, 0.82; W, 0.29; Re, 0.35; Ru, 0.34; Rh, 1.03; Ir, 0.14; Pd, 5.4; Pt, 0.97. It was found that generalization proposed by Kriessman & Callen (1954), gradient alternates sign successive columns periodic table, is not supported results this work. are discussed relation band theory metals and generalizations about d -band forms three metal series made.
