James Chadwick was an English physicist whose research with radioactivity pointed to the presence of a particle with no electrical charge in the nucleus of atoms. In those days, most researchers believed there were electrons within the nucleus as well as outside it.
Chadwick and some others, believed in the possibility that particles with no charge could be in the nucleus. This was the neutron and its discovery by Chadwick dramatically changed the course of science.
It made it possible to artificially create elements heavier than uranium. Chadwick received Nobel Prize in Physics in 1935 for this discovery.
James Chadwick led the British team in the Manhattan Project, in which the UK and Canada supported the United State’s World War II effort to build the world’s first nuclear bomb.
