Who discovered the neutron in 1932?

Explanation:
James Chadwick demonstrated the existence of the neutron in 1932. He showed that a neutral radiation produced when alpha particles hit beryllium could eject protons from materials, and by studying the energy of those protons and the fact that the radiation carried no charge, he deduced a neutral particle with nearly the same mass as a proton. This explained missing mass in the nucleus and paved the way for understanding isotopes and nuclear reactions. Rutherford, Bohr, and Curie made important contributions to atomic theory and radioactivity, but the specific discovery of the neutron came from Chadwick’s experiments.
