WebIt isn't different. For protons, the number always equals the atomic number of the element. Ions are atoms don't have the same number of electrons as protons. If you are told an atom has a +1 charge, that means there is one less electron than protons. If it has a -2 charge, there must be two more electrons than protons. WebThe electron is bound to the nucleus by the electric force, so you get quantized energy levels related to that "system" of nucleus + electrons. But inside the nucleus, the nucleons are bound to one another by the strong nuclear force, so you also get quantized energy levels for that smaller system. WebAug 19, 2024 · The atomic number defines the identity of an element. It describes the number of protons in the nucleus.
