  • Neutron - Wikipedia
    A neutron is a subatomic particle, symbol n or n0 , that has no electric charge, and a mass slightly greater than that of a proton The neutron was discovered by James Chadwick in 1932, leading to the discovery of nuclear fission in 1938, the first self-sustaining nuclear reactor (Chicago Pile-1, 1942), and the first nuclear weapon (Trinity, 1945)
