The Sun's atmosphere contains vast quantities of Het cations. These ions absorb some of the Sun's thermal energy, promoting electrons from the Het ground state to various excited states. A Het ion in the fifth energy level may return to the ground state by emitting three successive photons: an infrared photon (a = 1014 nm), a green photon (a = 469 nm), and an X ray (a = 26 nm). Calculate the excitation energy (in J) for the Het ion...
