WebNov 18, 2014 · Marco. Nov 18, 2014. James Chadwick played a vital role in the atomic theory, as he discovered the Neutron in atoms. Neutrons are located in the center of an atom, in the nucleus along with the protons. They have neither a positive nor negative charge, but contribute the the atomic weight with the same effect as a proton. Chadwick … WebFrom 1957 to 1962 he was a parttime member of the United Kingdom Atomic Energy Authority.
