Which value represents the first ionization energy of a nonmetal?
497.9kJ, 577.4kJ, 811.7kJ, or 1000.kJ ?
I think the answer is 1000. kJ, since it is the highest amount. Am I correct? My reasoning is that nonmetals have higher ionization energies than metals.

Yes that sounds reasonable to me. Although what about the noble gases? Don't they have a higher IE?

  Aren't noble gases nonmetals?
