  1. Question 1

    Q1. How does the penetration effect explain the energy level of 3s electrons compared to 3p electrons?

    • A) 3s electrons are closer to the nucleus
    • B) 3p electrons experience more shielding
    • C) 3s electrons have higher angular momentum
    • D) 3p electrons are more stable

    Answer: 3s electrons are closer to the nucleus

    Explanation: 3s orbital penetration allows s-electrons to approach the nucleus more closely than p-electrons.
