How was Neutron discovered?(Which experiment was used to discover the Neutron)
Answers
Answer:
A schematic diagram of the experiment used to discover the neutron in 1932. At left, a polonium source was used to irradiate beryllium with alpha particles, which induced an uncharged radiation. When this radiation struck paraffin wax, protons were ejected. The protons were observed using a small ionization chamber.

It is remarkable that the neutron was not discovered until 1932 when James Chadwick used scattering data to calculate the mass of this neutral particle. This analysis follows that for a headon elastic collision where a small particle strikes a much more massive one
An experimental breakthrough came in 1930 with the observation by Bothe and Becker that bombardment of beryllium with alpha particles from a radioactive source produced neutral radiation which was penetrating but non-ionizing

Answer:
James Chadwick discovered neutron during an experiment in which he had to track down the evidence of Rutherford's proton-electron pair.
Beryllium atoms were bombarded by alpha particles, it emits energetic radiations. The result of the experiment was that since neutrons are neutrally charged, they did not deflect the magnetic field.
In this way, neutrons were discovered.
