In 1932, J. Chadwick discovered neutrons, the neutral particles found in an atom. An experiment was performed by the physicist James Chadwick in which he bombarded Beryllium with alpha particles from Polonium’s normal radioactive decay.
- Neutrons are subatomic particles that are one of the primary constituents of atomic nuclei.
- The symbol n or no usually denotes them.
- Neutrons do not have any net electric charge associated with them. However, they have a mass that is slightly greater in magnitude than that of a proton.
- Neutrons play a major role in the mass and radioactive properties of atoms.
- One of the most significant applications of neutrons is in the excitation of delayed and triggered gamma rays from material components.
