Which subatomic particle was discovered by James Chadwick in 1932?

💡 Solution & Explanation

James Chadwick discovered the neutron in 1932 by bombarding beryllium with alpha particles, demonstrating the existence of a neutral subatomic particle with a mass nearly equal to that of a proton. J.J. Thomson discovered the electron and Ernest Rutherford identified the proton, separating them chronologically and experimentally from Chadwick's work.
