Quantum Chemistry and Spectroscopy - Quantum Chemistry 1.5 - Bohr Hydrogen Model 2: Energy

Short lecture on the Bohr hydrogen model energy. Bohr assumed the electron in the hydrogen atom travels in a fixed circular orbit with quantized angular momentum. By balancing the Coulomb force and centrifugal force acting on the electron, we can derive the radii, velocities, and energies of its allowed orbits. Transitions between these allowed energy levels leads to an expression which is in nearly exact agreement with the Rydberg formula, giving a value of the Rydberg constant which has extremely low error (~0.001%).
