If the ionisation energy of a hydrogen atom is 13.6 eV, its ionisation potential will be:
Correct answer: A. 13.6 V
- A. 13.6 V
- B. 136.0 V
- C. 3.4 V
- D. None of these options are correct
Explanation
Ionisation energy (IE) is the minimum energy needed to remove the outermost (valence) electron from an isolated, gaseous atom or molecule, forming a positive ion (cation). Ionisation energy is also called ionisation potential. Therefore, the ionisation energy will be equal to the ionisation potential, which is 13.6 V.

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.
