The electronic configuration of xenon regarding more external sub-levels (2+6),2 gives stability and inertia to xenon atom and it allows to understand the behaviour of subsequent chemical elements represented by transition elements including rare earths and actinides. The same thing happens for radon atom that has in external sub-levels the configuration (8+2),6. The prime difficulty in calculating energies of atomic electrons is no doubt the appraisal of effective shielding of internal electrons with regard to external electrons and it is important because that shielding reduces the size of nuclear charge that has to be considered in calculation.
