WebSep 13, 2006 · To find the number of neutrons in the future, simply use this formula: [9] N = M – n N = number of N eutrons M = … WebThe nucleus has nuclear energy levels, just like the atom has atomic energy levels. The reason for this is that you get energy levels whenever you have things bound together. The electron is bound to the nucleus by the electric force, so you get quantized energy levels related to that "system" of nucleus + electrons.
