POSITION OF THE TRANSITION SERIES ON THE PERIODIC CHART (in Spanish)
The "first transition series" is made up of the ten elements from scandium (Z = 21) to zinc (Z = 30). The electronic configurations of the first transition series elements are characterized by successive additions of electrons to the 3d level. Other transition series correspond to the first transition series in the subsequent periods. So then, lutetium (Z = 71) and the element 103, would occupy the place reserved for lanthanum (Z = 57) and actinium (Z = 89). The following modifications are proposed for the periodic chant: The subgroup III- a would be constituted by scandium (Z = 21), yttrium (Z == 39), lutetium (Z = 71) and element 103. Lantharide series and actinide series would be placed out of the subgroup III-a. Lainthanide series would be constituted by Lanthanum and the 13 elements that follow it. Actinide series would be constitated by actinium and the 13 elements that follow it. (auth)
