Final Answer:
- The center cluster of + and neutral particles is the
Nucleus.
- Inside the nucleus, the
+ particles are
Protons.
- Inside the nucleus, the neutral (no charge) particles are
Neutrons.
- The small
– particles moving in circles around the nucleus are
Electrons.
- The area where electrons move (the circles/shells) is the
Electron Cloud.
So the labels for the diagram should be:
- Arrow pointing to the whole central cluster →
Nucleus
- Arrow pointing to a
+ particle inside nucleus →
Proton
- Arrow pointing to a neutral particle inside nucleus →
Neutron
- Arrow pointing to a
– particle on an orbit →
Electron
- Arrow pointing to the outer region with orbits →
Electron Cloud
