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. WebApr 6, 2024 · The Bohr model and all of its successors describe the properties of atomic electrons in terms of a set of allowed (possible) values. Atoms absorb or emit radiation only when the electrons abruptly jump between allowed, or stationary, states.
