Sep 27, 2015 · A simple expression for the energy of an electron in the hydrogen atom is: E = − 13.6 n2 where the energy is in electron volts n is the principle quantum number. In the case of hydrogen, when the electron gains the right amount of energy, it moves to an orbital with principal energy level 2. The principal energy level defines the energy (and therefore the average distance from the nucleus) of the electron, but it does not specify the shape of the probability volume (the orbital). The energy lifts the atom's electron to an upper level. The electron then returns to its original orbit (drawn inward by the electrical attraction of the nucleus). The stored energy is released as light. Animation of atom emitting light . The rubber band analogy of storing energy can help you understand another feature of how atoms store energy.
