Nettet13. okt. 2024 · Limitations of Bohr’s Atomic Model The model was applicable to uni electron system only The model couldn’t explain the presence of fine line structures of different spectral lines of the hydrogen spectrum NettetSolution. First Postulate: Electron revolves round the nucleus in discrete circular orbits called stationary orbits without emission of radiant energy. These orbits are called stable orbits or non-radiating orbits. Second Postulate: Electrons revolve around the nucleus only in orbits in which their angular momentum is an integral multiple of h/2π.
NettetIn the Bohr plan, the electrons revolving around the nucleus are considered on a planar dimension. This is one of the biggest limitations of Bohrs model. It was later revealed that the dimension in which the electron moves around the nucleus is three dimensional. The biggest limitation of Bohr’s model was that it failed to make correct ...
