  1. Question 1

    Q1. What explains the lower electron affinity of fluorine compared to chlorine?

    • A) Smaller atomic radius
    • B) Higher ionization energy
    • C) Electron-electron repulsion
    • D) Lower metallic character

    Answer: Electron-electron repulsion

    Explanation: Fluorine's small size causes strong electron repulsion. Chlorine's larger size reduces repulsion, increasing EA.
