  1. Question 1

    Q1. What role does the Pauli exclusion principle play in spectral line formation?

    • A) Limits the number of electrons per energy level.
    • B) Determines photon spin during emission.
    • C) Prevents electron collisions in atomic gases.
    • D) Controls the rate of spontaneous emission.

    Answer: Limits the number of electrons per energy level.

    Explanation: Electron occupancy rules shape transition availability. Option B misattributes spin control to the exclusion principle.
