Which of the following is an integral multiple of h 2 in Bohr's model of an hydrogen atom?

Options

  1. ARadius of an atom
  2. BKinetic energy
  3. CPotential energy
  4. DAngular momentum

Correct answer

D. Angular momentum

Step-by-step solution

According to Bohr's quantization postulate, the angular momentum of an electron revolving in a stationary orbit is an integral multiple of h 2 . L = mvr = nh 2 where n = 1, 2, 3, Thus, angular momentum is an integral multiple of h 2 . Answer: Angular momentum
