J.J. Thompson developed one of the first mathematical models of the atom. Ernest Rutherford's experiments verified the structure of the nuclear atom. Neils Bohr developed an accurate mathematical model of the hydrogen atom.
After the discovery of the neutron in 1932, models for a nucleus composed of protons and neutrons were quickly developed by Dmitri Ivanenko and Werner Heisenberg. Almost all of the mass of an atom is located in the nucleus, with a very small contribution from the electron cloud.
