The Balmer series is obtained when all the transition of electrons terminate on:
Correct answer: C. 2nd orbit
- A. 1st orbit
- B. 3rd orbit
- C. 2nd orbit
- D. 4th orbit
Explanation
The Balmer series is a set of spectral lines in hydrogen atom's emission spectrum. These lines are the result of electronic transitions in hydrogen atoms, and they correspond to electrons moving to and from the 2nd orbit (n=2) to other higher energy orbits. These transitions result in the emission of visible light, which is why the Balmer series is prominent in the visible spectrum. So, option (b) is the correct choice for the termination of transitions in Balmer series.

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.
