Did You Know the Neutron Was Discovered by James Chadwick?

šŸ’” The Answer

  • In 1932, James Chadwick bombarded beryllium with alpha particles and observed neutral radiation.
  • He identified this radiation as neutrons, particles with mass similar to protons but no electric charge.
  • The discovery explained why atomic masses were greater than the number of protons.
  • Neutrons enable nuclear fission by being absorbed without electrostatic repulsion, starting chain reactions.
