When an electron undergoes a transition from a higher to lower state in singly ionized helium, how will the energy of the emitted photon compare with the analogous transition in hydrogen? Explain. (Select all that apply.)This happens because the helium atom has more neutrons.This happens because the helium atom has more protons.The transition energy will be higher in singly ionized helium.The transition energy will be lower in singly ionized helium.This happens because the helium nucleus is less massive
