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 E1,E2,E3\mathrm{E}_1, \mathrm{E}_2, \mathrm{E}_3, etc. These allowed states of constant energy are called the stationary states of atom
  3. CWhen an electron makes a transition from a higher energy stationary state to a lower energy stationary state, then it emits a photon of light
  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

The electron in a H-atom's stationary state moves in a spherical path.
