The kinetic energy of an electron in first Bohr radius of H-atom is:
Correct answer: B. 13.6eV
- A. 13.6J
- B. 13.6eV
- C. -13.6eV
- D. 13.6keV
- E. 13.6kJ
Explanation
The kinetic energy of an electron in the first Bohr radius of a hydrogen atom is 13.6 eV. The negative sign (-13.6 eV) is not used to represent the kinetic energy but rather the total energy (including both kinetic and potential energy) of the electron in the hydrogen atom.

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.
