Introduction
The Bohr model, also known as the Rutherford-Bohr model appears to be a relatively primitive model of the hydrogen atom when compared to the valence shell model. It is considered a semi-classical model of the atom because, in introducing quantized electron orbits, it unifies tangible mechanical concepts like velocity and kinetic energy with early quantum ideas. Despite its simplicity, it can sufficiently describe and explain atomic spectra and energy levels. However, it falls short in explaining multi-electron atoms and fine spectral details - limitations that Bohr was well aware of during its development.
