When an electron moves from a higher to a lower energy level, it releases a quantum of energy, which is what it had to absorb in order to make the jump in the first place. Thiâ¦s quantum of energy is often released in the form of a photon, which is a discrete amount of light of a certain wavelength.
Here's what happens... When a gaseous hydrogen atom in its ground state is excited by an input of energy, its electron is 'promoted' from the lowest energy level to one of higher energy. The atom does not remain excited but re-emits energy as electromagnetic radiation.ere's what happens...
