WebWhat does it mean to say that the energy of the electrons in an atom is quantized? Solution. Quantized energy means that the electrons can possess only certain discrete energy values; values between those quantized values are not permitted. Using the Bohr model, determine the energy, in joules, necessary to ionize a ground-state hydrogen atom.

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. WebWhen light shines on a metal, electrons can be ejected from the surface of the metal in a phenomenon known as the photoelectric effect. This process is also often referred to as photoemission, and the electrons that are ejected from the metal are called photoelectrons. In terms of their behavior and their properties, photoelectrons are no ...
