POSITIONS OF THORIUM AND URANIUM IN THE PERIODIC TABLE
During the course of a continuing investigation of the alloy behavior of Se and Ti group elements, it was noted that Th and U behaved as if they were members of the Ti group. Their crystal structure in intermetallic compounds was similar to that of members of the Ti group. U was found to bear little resemblance to Mo of the Cr group, as was earlier postulated: The concept in which both Th and U were considered members of the Ti group was not inconsistent with the hypothesis that Th, not Ac, is the parent element of the heavy-methl series. A radial periodic table was developed which showed Th in a dual role, first as a member of the Ti group, aad second, as the parent of a thoride series. (M.C.G.)
