Question
For the Li atom, the energy difference between the ground state and the first excited state, in which
the outermost electron is in a 2p orbital, is 2.96 x 1019 J. In the Li²+ ion, the energy difference
between the 2s and 2p levels is less than 0.00002 of this value. Explain this observation.
