  1. Question 1

    Q1. Which concept explains why s-orbital electrons shield outer electrons more effectively than p-orbital electrons?

    • A) Node count in orbitals
    • B) Penetration effect
    • C) Orbital angular momentum
    • D) Spin-orbit coupling

    Answer: Penetration effect

    Explanation: s-orbitals penetrate closer to the nucleus, providing better shielding. Option D is unrelated to shielding.
