Question
Which of the following postulate of Bohr's model of hydrogen atom is not in agreement with quantum mechanical model of an atom?
Select the correct option:
A
An atom can take only certain distinct energies ${{\rm{E}}_1},{{\rm{E}}_2},{{\rm{E}}_3}$, etc. These allowed states of constant energy are called the stationary states of atom
B
The electron in a H atom's stationary state moves in a circle around the nucleus
C
An atom in a stationary state does not emit electromagnetic radiation as long as it stays in the same state.
D
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
✓ Correct! Well done.
✗ Incorrect. Try again or view the solution.
Solution
The electron in a H-atom’s stationary state moves in a spherical path.
