James Chadwick discovered the Neutron in an atom. He hypothesized that there was something in the atom that has the same mass as a proton, but was neutral in energy. He used Beryllium atoms and bombarded it with alpha particles. Then an unknown radiation began to happen. It had a neutral energy source and soon became the neutron.
