The energy of an electron in the nth orbit of a hydrogen atom is?
Correct answer: D. None of these options is correct
- A. -0.0136 eV
- B. -1.136 eV
- C. 0.136 eV
- D. None of these options is correct
Explanation
The correct formula to calculate the energy of an electron in the nth orbit of a hydrogen atom is given by the Rydberg formula:En=−13.6 eV/ n2where En is the energy of the electron in the nth orbit and n is the principal quantum number. This formula yields discrete energy levels for the electron in the hydrogen atom.

About Dawn of Modern Physics
Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.
