The ionization potential of Hydrogen atom is:
Correct answer: A. 13.6 eV
- A. 13.6 eV
- B. 1.36 eV
- C. 10.2 eV
- D. 4.3 eV
Explanation
The ionization potential of a hydrogen atom is 13.6 eV, which is the energy needed to completely remove the electron from the nucleus when the atom is in its ground state. This value is derived from the Bohr model of the hydrogen atom. Other options like 1.36 eV, 10.2 eV, and 4.3 eV do not match the energy required to ionize hydrogen and are therefore incorrect.

About Spectrum of Hydrogen
The hydrogen spectrum consists of discrete emission lines produced when electrons fall between quantised energy levels and release photons. Questions use the Rydberg equation, photon energy and wavelength, and identify the Lyman, Balmer, Paschen, Brackett and Pfund series, which differ from continuous spectra.
