Explain why you expect the particles to take these paths. Since protons and neutrons are so much more massive than electrons, almost all of the mass of an atom comes from the nucleus, which contains all of the neutrons and protons. I used to enjoy chemistry from school life. It's easy to get a hydrogen atom with one proton and one neutron (deuterium), yet you won't find a helium atom with an atomic weight of 2 because this would mean the helium atom had two protons and zero neutrons!
