The Bohr Model, proposed by Niels Bohr in 1913, introduced several key postulates that transformed our understanding of atomic structure. Firstly, it suggested that electrons exist in specific quantized energy levels around the nucleus, rather than in continuous orbits. Secondly, it stated that electrons can only transition between these energy levels by either absorbing or emitting discrete amounts of energy in the form of photons. Lastly, the model asserted that the angular momentum of electrons is quantized and that electron orbits must be stable.

The Bohr Model had significant implications for explaining atomic spectra, particularly the emission and absorption spectra of hydrogen. It successfully explained the discrete nature of spectral lines and provided a mathematical framework for predicting the frequencies of emitted or absorbed photons during electron transitions. This model laid the foundation for understanding the electronic structure of atoms and played a crucial role in the development of quantum mechanics.
