    Q1. How does the Pauli Exclusion Principle apply to electrons in an orbital?

    • A) Maximum two electrons with opposite spins
    • B) Electrons must share same spin
    • C) Only one electron allowed per orbital
    • D) Electrons repel each other

    Answer: Maximum two electrons with opposite spins

    Explanation: Pauli limits two electrons per orbital with opposite spins. Hund's allows parallel spins first.
