THE CONSTITUTION OF LANTHANIDE SERIES, AND A DEDUCED LAW FOR THE ELECTRONIC CONFIGURATIONS OF THE SERIES' ELEMENTS (in Spanish)
It is generally admitted that the place of lanthanum in the periodic chant is in the subgroup III-a. By analogy to the distribution of elements in the periods 4 and 5, it is deduced that the subgroup mentioned is constituted only by scandium, yttrium, lutetium and element 103, that are the first terms of the transition series where the electronic levels 3d, 4d, 5d and 6d are completed. The subgroup II-a is formed by alkaline earth metals. In period 6, the lanthanide series would occupy a place between barium (alkaline eanth metal Z = 56) and lutetium (Z = 71). So, the elements of this series would be placed between the subgroup ll-a and the subgroup III-a. Their electronic configurations would be characterized by the filling of the 4f level. The lantharide series would be constituted by lanthanum and the 13 elements that follow it. Their position in the Periodic Chant would be out of the subgroup III- a, and not in this subgroup as the lanthanides are now situated. The electronic configurations of the lanthanide elements would satisfy the following law: (configuration of Xe) 4f n6s/sup 2/ (n = 1 to 14). The electronic configurations deduced by this formula coincide wtth the electronic configurations mentioned in 1958 by Seaborg, excepting the configurations of lanthanum and gadolinium. (auth)
