Photon emission. Illustration of an atom emitting a photon (glowing). The atom consists of a nucleus (pink), which contains neutrons and protons, and shells of electrons (blue). As an atom absorbs energy (top left) and becomes excited the electrons move further from the nucleus to higher energy orbits. Eventually the electrons will release this extra energy, as a photon, and return to their ground state.
