CEM 141 MSU EXAM 2 ACTUAL 2025/2026 QUESTIONS AND 100% CORRECT ANSWERS 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 - - Answer -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 protons and core electrons are not changed. However, when the number of electrons isNeed assistance on Online classes, Exams & Assignments? Reach out for instant help!!

Email now at: reduced, the repulsion between electrons decreases which results in a decrease in the radius of the electron cloud because the point at which attractions and repulsions are balanced is closer to the nucleus when there is less repulsion. When the radius of the electron cloud decreases, the strength of the attraction between the nucleus and the valence electrons increases which increases the amount of energy required to remove an electron (ionization energy). Which has a larger atomic radius? M
