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. WebVarious postulates of Bohr’s atomic model are: 1. In an atom, the electrons revolve around the nucleus in certain definite circular paths called orbits, or shells. 2. Each shell or orbit corresponds to a definite energy. Therefore, these circular orbits are also known as energy levels or energy shells. 3.
