D) Paschen, Balmer, Lyman.

Question

Quizplus · Accepted Answer

The sequence of the spectral line series emitted by excited hydrogen atoms, in order of decreasing energy of the lowest energy transition is Lyman, Balmer, Paschen. The Lyman series has the highest energy transition and is in the ultraviolet region of the electromagnetic spectrum. The Balmer series has a lower energy transition, and the emission lines are in the visible region. The Paschen series has the lowest energy transition and is in the infrared region of the electromagnetic spectrum. Therefore, the correct order of the hydrogen spectral line series is Lyman, Balmer, Paschen. Choice C is the only option that follows this order.
