[[fr:Niveau d'�nergie]]
An energy level is a quantified stable energy, which a physical system can have; the term is most commonly used in reference to the electron configuration of electrons, in atoms or molecules. According to quantum theory, only certain energy levels are possible; the higher an electron's level, the greater its potential energy.
