  1. Question 1

    Q1. Why can’t a hydrogen atom emit continuous spectra in the gaseous state?

    • A) Electrons exist in continuum energy states
    • B) Transitions are quantized due to discrete levels
    • C) Photons are absorbed by surrounding gas
    • D) Collisions prevent energy loss

    Answer: Transitions are quantized due to discrete levels

    Explanation: Discrete levels produce line spectra; A fails as continuum is only in solids/liquids.
