Is the Nucleus Fundamental?
Again, periodicity of nuclear properties...
mass, decay cascades,
suggest that nucleons fill quantum shells,
just like electrons in
the outer regions of atom
...look at chart
- Scientists found the nucleus composed of
- neutrons (n) discovered by
- and protons (p)
only differ in electric charge, mass (mn>mp)
- held together by (residual) strong
- broken apart by the weak force
