[SOLVED] Bohr Model of H-atom

Hi,

Would anyone be good enough to explain why the 1s2p splitting in a hydrogen atom is 3/4 of the total binding energy?

Would it have anything to do with the Rydberg energy?

E = - 13.6eV/n^2

I appear to have floated through my degree blissfully unaware of electronic configurations and their associated energies.

Regards,

That's the key. Use it to calculate the energy difference between the 1S and 2P states.

Ok, so

E(1s) = 13.6/1^2 = 13.6
E(2p) = 13.6/2^2 = 3.4

dE = E(1s)-E(2p) = 10.2

dE/E(1s) = 3/4

Thanks!
