ELECTRON CONFIGURATION AND IONIZATION ENERGY OF NEUTRAL ATOMS IN THE GROUND STATE William C. Martin The ground state electron configuration, ground level, and ion- ization energy of the elements hydrogen through rutherfordium are listed in this table. The electron configurations of elements heavier than neon are shortened by using rare-gas element sym- bols in brackets to represent the corresponding electrons. See the references for details of the notation for Pa, U, and Np. Ionization energies to higher states (and more precise values of the first ion- ization energy for certain elements) may be found in the table “Ionization Energies of Atoms and Atomic Ions” in Section 10 of this Handbook .
