Who discovered the fundamental subatomic particle neutron?


The neutron was discovered by James Chadwick by bombarding a thin sheet of beryllium by α-particles.


  • Neutrons are subatomic particles that are one of the primary constituents of atomic nuclei. They are usually denoted by the symbol n or no.
  • Neutrons do not have any net electric charge associated with them.
  • Inside the nucleus of the atom, the protons and the neutrons are bound together via nuclear forces. For the stability of atomic nuclei, the presence of neutrons is a must.
  • The only exception to this rule is the protium nucleus.
  • One of the most important applications of neutrons is in nuclear reactors to facilitate nuclear fission reactions, and in some cases, nuclear fusion reactions.
