WebPostulates of Bohr’s Atomic Model The three Postulates stated by Neil Bohr are: The electron can revolve in certain stable orbits around the Nucleus without radiating any energy, in contrast to what classical electromagnetism suggests. The stable orbits are called stationary orbits. They are gained at certain distinct distances from the nucleus. 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.
