Postulates of bohr's model of hydrogen atom
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. Web12 Apr 2024 · Bohr's postulates include:-1. Electrons in an atom move in circular orbits around the nucleus, and their motion is quantized. ... These postulates form the basis of the Bohr model of the hydrogen atom.
