WebPostulates of Bohr’s Atomic Model: [Click Here for Sample Questions] The main postulates of Bohr’s Atomic Model are as follows: The electrons move around the nucleus in certain permitted circular paths known as orbits.; Each orbit is associated with a definite amount of energy and therefore, these are known as energy levels or energy states. The energy levels … Web3 Apr 2024 · Complete answer: The postulates of Bohr's theory are as follows: 1) The electrons in an atom revolve around the nucleus only in certain selected circular orbits. As long as the electrons remain in a particular orbit, it neither loses or gains energy.
