CEM 141 MSU Exam 2 Questions and Answers Already Passed Which reaction requires the most energy? A. N(g) → N+(g) + e - B. N+(g) → N2+(g) + e - C. F(g) → F+(g) + e - D. F+(g) → F2+(g) + e - D. F+(g) → F2+(g) + e - Fluorine has a higher effective nuclear charge than Nitrogen - so it is harder to remove an electron (takes more energy because the electron is more strongly attracted by the nucleus). Effective nuclear charge is the same for F and F+ because the number of pro...
