WebDanish physicist Niels Bohr (1885–1962) in 1913 created a model that allowed electrons to travel without losing energy by going in defined orbits. He related it to the orbits of planets around the Sun. This model fit much of the data at that time; a nucleus with protons and … WebIn 1932, the physicist James Chadwick conducted an experiment in which he bombarded Beryllium with alpha particles from the natural radioactive decay of Polonium. The resulting radiation showed high penetration through a lead shield, which could not be explained …
