MDCAT Chemistry MCQ #801

  1. Question 1

    Q1. Why does the electron affinity of beryllium remain low despite being in Group 2?

    • A) Large atomic radius
    • B) High ionization energy
    • C) Empty p-orbital for electron addition
    • D) Fully filled s-orbital configuration

    Answer: Fully filled s-orbital configuration

    Explanation: Be has a fully filled 2s orbital, making electron addition less favorable. Option A is partially correct but not primary.
