Nucleus

The nucleus:

1. Rutherford's gold leaf experiment and the discovery of the nucleus          Closest approach          Size and mass  of the nucleus

2. Proton        Neutron           Mass number           Isotopes          Atomic number         Periodic table        

3. Radius  of the nuclei (constant mass density)         V = V0 * A    Radius  of the nuclei  (electron diffraction)          Properties of the strong nuclear force
