What is the relative fraction of H atoms that are ionized in stars with surface T=5800K and 11300K (the atmospheres were assumed to have the same pressure P=200 dynes per cm^2).

a. Find the relative number of neutral HI atoms in the first excited state (n=2) to those in the ground state (n=1).

b. Find the relative number of atoms in the stars atmosphere (i.e BOTH neutral and ionized).
