Limitations of bohr model class 12

NettetIn this Physics video in Hindi for Class 12 we explained some of the limitations of Bohr's atomic model. This is a topic from Chapter 12 : 'Atoms' for Class ... 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.

Bohr’s model of the hydrogen atom was no doubt an improvement over Rutherford’s nuclear model, as it could account for the stability and line spectra of a hydrogen atom and hydrogen-like ions (for example, and so on). Merits of … Nettet5. apr. 2024 · Bohr combined classical and early quantum mechanics concepts to propose a three-postulate theory. These postulates are: 1. An electron in an atom revolves in certain stable orbits without emitting radiant energy. Each atom has certain definite stable orbits. Electrons can exist in these orbits.
