WebFeb 9, 2016 · Chadwick didn't discover the neutron on purpose, of course. After the discovery of the nucleus by Rutherford in 1911, alpha particles were used to probe its structure. These kind of experiments were pioneered by Rutherford himself (as an example, he discovered in 1917 that the nitrogen nucleus contains hydrogen nuclei, i.e. protons).

WebIn 1914, Bohr suggested that electrons could exist only in certain orbits inside the atom. This meant that there was a mathematical connection between atomic orbitals and wavelengths or frequencies of light. Later, in 1916, Bohr suggested that the atom is mainly made of neutrons.
