Ground-state electron configurations of the elements in agreement with the extended periodic table suggested by Jeries A. Rihani with emphasis on the principle of half-filled and completely-filled orbitals. Note that some of these configurations are uncertain and that the high atomic numbers beyond 125 might be impossible to synthesize experimentally.
