Accurate Hartree–Fock computations were carried out long ago on all the atoms in the periodic table [1]. From these results, Wang and Parr [2] have plotted radial distribution functions (RDFs) , where is the total electron density, for the noble gas atoms He (), Ne (), Ar (), Kr (), and Xe (). These are shown as insets in the graphics. The shell structure of the electron distributions is evident, and can be identified with the K, L, M, N, and O shells, corresponding to principal quantum numbers 1 to 5, respectively.
