The energy levels of the hydrogen atom are given by En=-me4/(32[tex]\pi[/tex]2[tex]\epsilon[/tex]ohbarn2, and are independant of the orbital angular momentum quantum number l, yet the Aufbau principle clealry implies that the energies of s, p, and d orbitals are different. Explain this apparent paradox and provide an example of experimental evidence that supports your conclusion. I feel like I'm on the right track if I go about it from a shielding/penetration standpoint. But I could use the additional help! Thanks!
