Since H and D have different reduced masses, they also have slightly different electronic energy levels. Calculate (a) the ionization potentials and (b) the wavelength of the first line in the Balmer series for these atoms.

There is one s orbital, and there are three p orbitals, five d orbitals, and seven f orbitals. thus, the answer is b. do not confuse the number of orbitals in a subshell with the number of electrons the subshell can hold. each orbital can hold two electrons, so the capacity of an nf subshell is 14 electrons.

What are the options? i can you if you give them.
