Expert Answer:

Discovery of the Neutron:

  • In 1932, James Chadwick observed that when beryllium was exposed to α-particles, different kinds of particles were emitted.
  • These particles had about the same mass as protons and carried no electrical charge.
  • Hence, Chadwick named this particle as neutron.
  • It was present in the nucleus along with the proton.
  • A neutron is represented by letter n.
  • Neutrons are present in the nucleus of all the atoms except hydrogen.
  • As protons and neutrons are both present in the nucleus, they are together known as nucleons.
