Protons and neutrons go in the nucleus (center). Example: Electrons go in energy levels of the electron cloud. The first energy level only holds up to 2 electrons. The second energy level holds up to 8 electrons. The third energy level holds up to 8 electrons. The forth energy level will hold 18 . BUT you only count 2. Example for carbon: 6 ...
