Which of the following postulate of Bohr's model of hydrogen atom in not in agreement with quantum mechanical model of an atom ?

Options

  1. AAn atom in a stationary state does not emit electromagnetic radiation as long as it stays in the same state
  2. BAn atom can take only certain distinct energies E ₁, E ₂, E ₃ , etc. These allowed states of constant energy a
  3. CWhen an electron makes a transition from a higher energy stationary state to a lower energy stationary state,
  4. DThe electron in a H atom's stationary state moves in a circle around the nucleus

Correct answer

D. The electron in a H atom's stationary state moves in a circle around the nucleus

Step-by-step solution
