Electron configurations lighter atoms

The development of correlation schemes at the highest levels of theory (the CCSD(T) technique) allowed for very accurate DCB predictions of atomic properties for the heaviest elements up to Z=122 (see Chapter 2 in this book). Reliable electronic configurations were obtained assuring the position of the superheavy elements in the Periodic Table. Accurate ionization potentials, electron affinities and energies of electronic transitions (with the accuracy of below 0.01 eV) are presently available and can be used to assess the similarity between the heaviest elements and their lighter homologs in the Periodic Table. 

The electron configurations of ions consisting of only one atom can be shown in the same way as illustrated for atoms above. For the lighter elements, the electron... 

Electronic configurations, ionization potentials, atomic/ionic radii, polarizabilities and stability of oxidation states are important chemical properties, whose knowledge is indispensable in assessing similarity of the heaviest elements to their lighter homologs in the chemical groups.
