Nuclei

Having discussed the theoretical models of the atom as a whole in the previous sections - Thomson's watermelon model, Rutherford's alpha-scattering-derived nuclear model, and Bohr's quantised orbital model - the unit now turns its attention specifically to the structure and properties of the nucleus at the centre of the atom: its composition, its classification into isotopes/isobars/isotones, its size and density, its mass defect and binding energy, and ultim …
