James Chadwick 1932
Experiment:
James Chadwick became interested in the experiments Frederic and Irene Joliot-Curie were conducting in Europe. He decided to conduct his own experiment, and this resulted in Chadwick finding the neutron.
James Chadwick conducted his experiment by projecting alpha particles at Beryllium. Neutrons flew out of the Beryllium, causing the neutrons to hit paraffin wax. When the neutrons hit the wax, protons flew out and went to the detector. At first, Chadwick didn’t know what the first particles were. After further research and experimenting, James Chadwick discovered that the particles had no charge. Since the subatomic particle had a neutral charge, Chadwick named the particle neutron. |
