Question

Which of the following postulate of Bohr’s model of hydrogen atom is not in agreement with quantum mechanical model of an atom? (A) The electron in a H atom’s stationary state moves in a circle around the nucleus. (B) An atom can take only certain distinct energies E1, E2, E3, 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) An atom in a stationary state does not emit electromagnetic radiation as Long as it stays in the same state.
