WebNov 16, 2024 · The main postulates of Bohr’s model of atom are as follows: The electrons move around the nucleus with definite velocity in a certain fixed closed circular path called orbits (or) shells. These shells are numbered as one, two, three, four or termed as \ (\rm {K, L, M, N}\) from the nucleus. 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.
