Use the Saha equation to determine the fraction of Hydrogen atoms that are ionized NI/Ntotal at the center of the Sun, where the temperature is 15.7 million K and the electron number density is ne=6.1x1031 /m³. Don't try to compare your result with actual data, as your result will be lower due to not taking the pressure into account. Since most of the neutral H atoms are in the ground state, use Zdegeneracy=2 and, since a H ion is just a proton, Zi=1. Also, use Xi=13.6 eV.
