Abstract

Twelve arguments based on or associated with electron configurations of the d or f block elements, absent of any other considerations, support (a) cerium-thorium and lutetium-lawrencium as the first and last dyads of the f-block; and hence (b) Group 3 as Sc-Y-La-Ac, on regularity grounds. The least common form of periodic table with Group 3 as Sc-Y-Lu-Lr does not accommodate the impact of the delayed appearance of the first f electron.
