Which of the following postulate of Bohr's model of hydrogen atom in not in agreement with quantum mechanical model of an atom ?
- A An atom in a stationary state does not emit electromagnetic radiation as long as it stays in the same state
- B An atom can take only certain distinct energies \(\mathrm{E}_1, \mathrm{E}_2, \mathrm{E}_3\), etc. These allowed states of constant energy are called the stationary states of atom
- C When an electron makes a transition from a higher energy stationary state to a lower energy stationary state, then it emits a photon of light
- D The electron in a H atom's stationary state moves in a circle around the nucleus
