If an electron in an excited hydrogen atom is occupying the 5th energy level and then relaxes back to the ground state, how much energy is released in the form of electromagnetic radiation? c) d) Consider the energy gaps between the energy levels in the graph above. Do the relative energies of the shells converge or diverge as n increases. Why might the observed trend occur? e) Indicate which orbital transitions are associated with the 4 lines in the visible hydrogen line spectrum
