It would appear from the fonn of the table that there should be a repetition of this double inter- ruption in period 7. Perhaps the elements Th, Pa, and U are out of place and should be placed in the third class, the rare earth elements, under Ce, Pr

been the lack of suitable forms or charts for the record- ing of such data. Another factor that has retarded the use of such presentation has been the disregard by many investigators of the fact that compounds of the elements exhibit similar characte

A rational explanation for this relationship may be found in recent developments of Bohr's theory of atomic constitution.' If metals are defined as elements whose atoms react by loss of valence electrons, then the most active element is the one that
