Energy levels of hydrogenic orbitals summary

As mentioned previously, energy E appears only in the radial equation [eq. (2.1.14)], which does not involve Hence we readily note that s orbitals are non-degenerate, p orbitals are triply degenerate, d orbitals have fivefold degeneracy, and f orbitals have sevenfold degeneracy. As it turns out, for the hydrogen atom only, E is also independent of l  

To summarize, each hydrogenic orbital is described by three quantum numbers and each quantum number is responsible for some properties  

Comparing the results of the Bohr and the wave mechanical models, we find that
