The second ionisation potential of Be is 17 98 eV If the electron in Bet is assumed to move in spherical orbit with a central field of effective nuclear charge Zeff consisting of the nucleus and other electrons If the extent of shielding by the K electrons of Li atom is same as calculated above the ionisation potential of Li will be 1 10 2 eV 3 5 746 eV 2 3 476 eV 4 3 2 eV
