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.
When electrons gain or lose energy, they jump between energy levels as they are rotating around the nucleus. For example, as electrons gain energy, they might move from the second to the third level. Then, as they lose energy, they might move back to the second level or even to the first energy level. Only a certain number of electrons can be in an energy level at the same time. The photon shown in the graphic can be considered a small bundle of energy. (For more information on atoms, you may want to review the materials on magnetism.) Review: Electrons spin and rotate around the outside of the nucleus.
