Abstract
The moments and for are derived from comprehensive Hartree-Slater oscillator-stength distributions for He through Ar. For , these moments are governed by valence excitations only, and therefore exhibit a pronounced periodic variation that repeats in each row. Inner shells begin to contribute appreciably to , which retains a periodic variation superimposed upon an over - all increase with increasing atomic number . For , the dependence of the moments becomes dominated by inner-shell contributions; as increases, the over-all increase with becomes more rapid. Another perspective of the voluminous data is gained by plotting vs . The plot reveals three classes of behavior—"tight," "intermediate," and "loose" atoms. Comparisons with experiment and more detailed calculations are made where possible.
