A new periodic table based on the energy sequence of atomic orbitals  Walker, W. R.; Curthoys, G. C.
Since the theory of atomic and molecular orbitals has proven to be of such value in interpreting the data of inorganic chemistry, it is hoped that a new periodic table based on the energy sequence of atomic orbitals will be an aid to the further systematizing of chemical knowledge.

The periodic table: The 6d-5f mixed transition group  Coryell, Charles D.
With relatively few modifications, the Bohr-type periodic table presented by Glocker and Popov can be made to reflect more instructively the rather complex relationships obtained in the neighborhood of the 4f or gadolinium transition group and, more importantly, in the 6d-5f sequence extending from actinium through the region of uranium and the synthetic earths to element 103.
