The spectral series that contains transitions terminating on the ground hydrogen is called:
Correct answer: D. Lyman series
- A. Paschen series
- B. Balmer series
- C. Pfund series
- D. Lyman series
Explanation
The spectral series that contains transition terminating on the ground state (lowest energy level) of a hydrogen atom is called the "Lyman series." In the Lyman series, electrons transition to the n = 1 energy level, which is the ground state for hydrogen. These transitions result in the emission of ultraviolet light, and the Lyman series includes the lines in the hydrogen spectrum that correspond to these transitions. The Lyman series is one of the most well-known and historically significant series in atomic physics and spectroscopy.

About Atomic Spectra
Atoms emit or absorb light at specific wavelengths because electrons occupy quantized energy levels and change levels by absorbing or releasing photons. The topic covers emission and absorption spectra, spectral series, hydrogen’s line spectrum, energy-level transitions, and the relation between wavelength, frequency and photon energy.
