Chemistry
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.

Consider a system of three molecules A, B, and C. Suppose that three units of energy can be distributed over the three atoms. Each atom can have no energy, one unit of energy, two units of energy, or all three units of energy. Assume that each of the ten possible arrangements ...
