Web3 Aug 2024 · Write the postulates of Bohr’s Atomic Model. (Diagram is not necessary) (5) Ans. Postulates of Bohr Atomic Model 1. The electron in an atom revolves around the nucleus in one of the circular orbits. Each orbit has fixed energy. WebThe main postulates of Neil’s Bohr are as follows. In atoms, electrons revolve around the nucleus in special orbits called discrete orbits or shells or energy levels. While the electrons revolve, they do not radiate energy. The circular orbits are numbered as 1,2,3,4 or designated as K, L, M, N shells.
