WebDec 16, 2024 · The Bohr Model of the Hydrogen Atom attempts to fill in some of the gaps left by Rutherford’s model. It has a special place in history because it introduced the quantum theory, which gave rise to quantum mechanics. In comparison to the valence shell atom model, the Bohr model is a more rudimentary representation of the hydrogen atom. WebMar 5, 2024 · The energy of the atom is the sum of the mutual potential energy between nucleus and electron and the orbital kinetic energies of the two particles. That is: E = − Ze2 4πϵ0a + 1 2mv2 + 1 2M(mv M)2. If we make use of equation 7.4.2 this becomes. E = − m(M + m)v2 M + 1 2mv2 + 1 2m2 M v2.

Sommerfeld (in 1916) expanded on Bohr’s ideas by introducing elliptical orbits into Bohr’s model. Sommerfeld’s improvement allowed the Bohr model to explain the splitting of the Balmer lines when the hydrogen atom was in an electric field. Electric field splitting of lines is known as the Stark effect.
