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 
, etc. These allowed states of constant energy are called the stationary states of atom
, 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
