Sanderson's Periodic Table of the Chemical Elements

Sanderson's 1967 formulation has both the d-block elements and the f-block elements totally removed from the body of the table thus allowing the elements in the Major Groups of Periods 4, 5 and 6 to be grouped with the "typical" elements of Periods 2 and 3.

The Inner Transition elements are from Ce to Yb, i.e., in this 'rational' arrangement there are only thirteen lanthanide metals.

From Michael Laing's paper: A Revised Periodic Table with the Lanthanides Repositioned, Found. Chem. (2005) 7: 203-233
