1972 Ap Chemistry Free Upd Response Answers -

The ionization energy of nitrogen is greater than that of oxygen because the electron removed from oxygen comes from a $p$ orbital that is slightly shielded by the other $p$ electrons, making it easier to remove. In contrast, the electron in nitrogen is removed from a more stable, half-filled $p$ subshell.
