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.
