WebSep 21, 2024 · Bohr's Model In 1913, a Danish physicist, Niels Bohr (1885–1962; Nobel Prize in Physics, 1922), proposed a theoretical model for the hydrogen atom that explained its emission spectrum. Bohr’s model required only one assumption: The electron moves around the nucleus in circular orbits that can have only certain allowed radii. WebPostulates of Bohr Atomic Model. Electrons revolve around the nucleus in a fixed circular path termed “orbits” or “shells” or “energy level.”. The orbits are termed as “stationary orbit.”. Every circular orbit will have a certain amount of fixed energy and these circular orbits were termed orbital shells. The electrons will not ...
