A. Predict the ionization energy of Be3+ in its ground state given that the ionization energy of Li2+ in its ground state is 122:45 eV. Notice that the number of protons and neutrons in the nuclei of both Li and Be make their nuclear masses effectively in nite compared with the mass of the electron. b. What is the ionization energy expressed in atomic units for a Li2+ ion in a 4py electronic state?
