WebThis theory was adopted by Niels Bohr in 1913 who theorised that electrons could orbit the nucleus in a circular orbits and that the distance of the electron to the nucleus was fixed unless it moved between energy levels with the absorption or emission of light. This conclusion led to the theory that electrons exist in energy levels around the ... WebSep 25, 2024 · Once reunited after the war, Chadwick and Ellis embarked on a replication of Chadwick’s, 1914 experiment, and in 1922 they published a report on their results. As they explained, their experimental apparatus “was identical in principle with that used by Chadwick” in 1914.
