WebHow were neutrons discovered? James Chadwick (1891-1974) was awarded with the Nobel Prize in physics in 1935 for the discovery of the neutron. (Photo: nobelprize.org) In 1932, the physicist James Chadwick conducted an experiment in which he bombarded Beryllium with alpha particles from the natural radioactive decay of Polonium. WebHe established that an atom includes a tiny, positively charge nucleus, which is surrounded by electrons. Both John Dalton and Ernest Rutherford, among other great researchers and scientists, assisted in creating the atomic theory that exists today. Dalton's theory was the first modern atomic theory, but a part of it was disproven by Rutherford.

He performed the beryllium bombardment experiments himself and interpreted that radiation as … WebJ. J. Thomson took science to new heights with his 1897 discovery of the electron – the first subatomic particle.
