Variation of Orbital Radii with Atomic Number

From Jour. Fac. Sci., Hokkaido Univ., Ser. IV. vol. 22, no. 2, Aug., 1987, pp. 357-385, The Connection Between the Properties of Elements and Compounds; Mineralogical-Crystallochemical Classification of Elements by Alexander A. Godovikov & Yu Hariya.

The analyses of the variations of the orbital atomic radii values (r_orb) with the increase of the atomic number (Z) allow establishment of the following recurring regularities of their change:
