In the absence of the exchange energy, the degeneracy between 1s¹2s¹ and 1s¹2p¹ configurations would only be lifted by
relativistic corrections.
For a given configuration and L the exchange energy favours (ie the energy is lower for) S-1 compared with S=0
O
For a given configuration and L the exchange energy favours states that are spatially anti-symmetric
The exchange energy gives larger shifts in the levels than relativistic corrections
L, S remain good quantum numbers in the presence of the exchange energy

The three lowest energy levels of a hydrogen atom are -13.6 eV, -3.4 eV, and -1.5 eV. Assume that there is only one way to occupy any one of these levels.
Calculate the relative probability that a hydrogen atom in thermal equilibrium in a star, at temperature T = 9674 K, is in its first excited state (at -3.4 eV) relative to its ground state (at -13.6 eV).
Write your answer in exponential form.
Recall that Boltzmann's constant can be written as 8.617 x 10-5 eV K-1.
