The orbital energies for Ne and Ar determined by the Hartree-Fock Self- Consistent Field method are given in the table below. Ne: Orbital E, (kJ/mol) 1s -86.0 2s -5.06 2p -1.94 Ar: Is -311.35 2s -32.35 2p -25.12 3s -3.36 3p -1.65 a. Estimate the first ionization enerav for each element. b. Explain the "trend" in ionization energy you obtained in part "a." (Which element is easier to ionize and why.)
