WebFor example, if an electron jumps from a higher to a lower energy level, the lost energy will have to go somewhere and in fact will be emitted by the atom in a bundle of electromagnetic radiation. This bundle is known as a photon, and this emission of photons with a change of energy levels is the process by which atoms emit light. See also laser. WebAll elements either emit or absorb certain frequencies of light. Evidence from atomic line spectra supports the Bohr model of the atom using photon frequency calculations.

WebApr 15, 2024 · At temperatures higher than a few hundred degrees, electrons will gain energy and move to a higher shell, but only momentarily.
