= A very hot star has surface temperature T = 100,000 K. The element unobtanium has ionization potential X 862 eV and three states with E₁ = 0, E2 = 8.62 eV, and E3 = 17.24 eV. The statistical weights of each level are g = 2n², and ne ( 1 (2πmekT h2 3/2 = 10-5. What fraction of the unobtanium atoms will be neutral and in the n = 2 state? Express your answer in terms of e (the base of the natural log).
