ABSTRACT

Unlike other groups of elements, Group 3 constituency remains unsettled. This article argues that ground level microstates and atomic number parity suggest Sc-Y-Lu-Lr Group 3 membership.

KEYWORDS

Transition metals, inner transition elements, lawrencium placement, rare earth metals, group 3 constituents, ground level, atomic microstates, atomic number, parity, f-block.
