Atomic and Nuclear Structure

The 'Rutherford' model for the atom proposed that an atom consisted of a very small positive nucleus surrounded by a much larger volume, occupied by an appropriate number of electrons. We now know that the nucleus consists of protons and neutrons held together by strong short range forces.

This module reviews the forces which operate between atomic particles, the nuclear reactions that can cause atomic transformations, and the behaviour of electrons in the Bohr model of the atom.
