  Relativistic effective atomic configurations of superheavy elements Cn, Nh
and Fl and their lighter homologues (Hg, Tl and Pb) in their simple compounds
with fluorine and oxygen are determined using the analysis of local properties
of molecular Kohn-Sham density matrices in the vicinity of heavy nuclei. The
difference in populations of atomic spinors with the same orbital angular
momentum and different total angular momenta is demonstrated to be essential
for understanding the peculiarities of chemical bonding in superheavy element
compounds. The results are fully compatible with those obtained by the
relativistic iterative version of conventional projection analysis of global
density matrices.
