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. WebBohr’s model of an atom was the first model to incorporate the quantization of energy. It gave results similar to those obtained experimentally for hydrogen atoms. However, Bohr’s model had certain limitations. Limitations of the Bohr’s Atomic Model Bohr’s atomic model explains many features of the atomic theory, but it has its limitations.
