WebThe postulates of Bohr's model of an atom are 1. Electrons revolve around the nucleus of an atom in a certain definite path called the Orbit or stationary state of the shell. 2. The shells are having different energy levels denoted as K, L, M, N. 3. As long as the electron remains in an orbit, it neither absorbs nor emits energy. 4. WebIn 1913, Niels Bohr proposed the idea of a hydrogen atom, based on the quantum assumption that a certain body part takes only different amounts. Electrons revolve around the nucleus, but only in fixed lines, and When electrons cross the low-energy path, the difference is sent as radiation.
