WebThe Bohr model only worked for Hydrogen atoms, and even for hydrogen it left a lot unexplained. The reason it works somewhat for hydrogen is that even though the electrons are not in orbits there are certain energy concepts for orbits that have more universal applicability. 2 comments ( 3 votes) April Tucay 8 years ago WebBohr’s expression for the quantized energies is: En = − k n2,n= 1,2,3,….

WebThe Bohr model is a relatively primitive model of the hydrogen atom, compared to the valence shell model. As a theory, it can be derived as a first-order approximation of the hydrogen atom using the broader and … WebBohr could now precisely describe the processes of absorption and emission in terms of electronic structure. According to Bohr's model, an electron would absorb energy in the form of photons to get excited to a higher energy level as long as the photon's energy was equal to the energy difference between the initial and final energy levels.
