Ionization energy of hydrogen atom is:
Correct answer: D. 13.6eV
- A. 0.54eV
- B. 0.85eV
- C. 3.39eV
- D. 13.6eV
Explanation
The ionization energy for hydrogen is 2.18 x 10-18 Joules which when divided by 1.60 x 10-19 Joules/eV gives us 13.6 eV.

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.
