An Ionic atom which is equivalent to hydrogen atom has wavelength equal to 1/4th of hydrogen lines is
Correct answer: A. He+
- A. He+
- B. Li++
- C. Ne+9
- D. Na10+
Explanation
Given that the wavelength of the atom is 1/4 of the wavelength of the hydrogen. Z = 2 and this is for Helium ion.

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.
