... Problem 3: Spectrum of Alkali Atoms (10 points) We have seen that the spectrum of hydrogen has an “accidental” degeneracy – states with the same principle quantum number n, but different angular momentum quantum number l are degenerate. This was an artifact of the pure 1/r Coulomb potential associa ...

Bohr`s atomic model
... An orbiting electron must have a whole number of wavelengths around the circumference of its orbit (6), otherwise the wave will interfere destructively with itself. This approach predicts the same energy levels as Bohr’s model. (You can use Box 2 to show that Equations 1 and 2 are equivalent.) ...
