For a H-atom which one of the following statements is correct?

Correct answer: B. The angular momentum is n times h/2π

  • A. The radius of the orbits are integral multiple of the Bohr-radius ...... 0.053mm
  • B. The angular momentum is n times h/2π
  • C. The energy in the nth-orbit is n times the ground state energy.
  • D. Missing

Explanation

This option is correct as the angular momentum is n times h/2pi which is given by the formula : L=nh/2pi or mvr=nh/2pi which is stated in one of the Bohr's postulate. It can have only quantized values which are situated with the orbits rather having values in between the orbits.

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.
