Energy level chemistry definition
WebThe term energy level is most commonly used in reference to the electron configuration in atoms or molecules. In other words, the energy spectrum can be quantized (see continuous spectrum for the more general case). As with classical potentials, the potential energy is usually set to zero at infinity, leading to a negative potential energy for ... WebIn chemistry, sublevels refer to energies associated with electrons. In physics, sublevels may also refer to energies associated with the nucleus. Niels Bohr's earliest quantum …
