  1. Question 1

    Q1. What is the primary reason for the difference in electron affinity between fluorine and chlorine?

    • A) Fluorine has a smaller atomic radius
    • B) Chlorine has better shielding
    • C) Electron-electron repulsion in fluorine's small size
    • D) Higher nuclear charge in fluorine

    Answer: Electron-electron repulsion in fluorine's small size

    Explanation: Fluorine's small size causes repulsion in the added electron. Chlorine's larger size mitigates this effect.
