The existence of the neutron was proposed by the British physicist James Chadwick in 1932. His discovery came after experiments showed that there were particles in the atomic nucleus that had no charge, which explained the missing mass in atoms that could not be accounted for by protons alone. Chadwick's work confirmed the neutron as a fundamental component of atomic structure, leading to significant advancements in nuclear physics.
