The energy required to ionize … WebElectrons, if given the chance, will fall towards the lowest energy level they can. So our electron will fall back down to the ground state and give up four eV of energy. The way an electron can give up energy is by emitting a photon. So after falling back down to the ground state, this electron would emit a four eV photon.
