question

A chemist has one mole of X atoms. He finds that when half of the X atoms transfer one electron to the other half, 409 kJ must be added. If all of the resulting X^- ions are subsequently converted to X+ ions, an additional 733 kJ must be added. Find the ionization potential, and the electron affinity of X.
