Problem
A He+ ion (Z=2, one electron) is prepared in the level n=2. Spin is not included in this count.
((a)) List the allowed values of l for n=2.
((b)) For each l, list the allowed ml values and the spectroscopic label of the sub-level.
((c)) State the total number of states and check against n2. Explain briefly why this count does not depend on Z.
