why bohr model was rejected? Related:  Introduction to Atomic Structure: Various Models of Atom?

Answer

Introduction to the Bohr Model
The Bohr model, proposed by Niels Bohr in 1913, was a significant advancement in atomic theory. It introduced quantized energy levels for electrons, allowing for a clearer understanding of atomic structure and the emission spectra of hydrogen.
Reasons for Rejection of the Bohr Model
Despite its contributions, the Bohr model faced criticism and was eventually rejected for several reasons:

Limited Applicability: The Bohr model effectively explained the hydrogen atom but failed to account for more complex atoms with multiple electrons.
Electron Behavior: The model treated electrons as particles in fixed orbits, neglecting their wave-like nature as described by quantum mechanics.
Inconsistent with Quantum Mechanics: The Bohr model did not incorporate the principles of wave-particle duality and uncertainty, which are fundamental to modern quantum mechanics.
Energy Levels: While the Bohr model introduced discrete energy levels, it could not accurately predict the energy levels for atoms with more than one electron.
Spectral Lines: The model could not explain the fine structure and hyperfine splitting observed in spectral lines, which required a more advanced understanding of atomic interactions.

Conclusion
The Bohr model laid the groundwork for future atomic theories, but its limitations prompted the development of more sophisticated models, such as the quantum mechanical model, which better describe electron behavior and atomic structure. This evolution reflects the ongoing quest for understanding the complexities of the atomic world.

Answer

Bohr model was rejected because the model talks about electron orbiting in circular orbit, whereas in quantum mechanics orbit is the region of maximum probability where an electron can be found. electrons are not found in a particular place but there is the probability of electron being in that place.
