JEE Main 20253 Apr, Morning shiftChemistryEasyAtomic Structure113× since 2002Which of the following postulate of Bohr's model of hydrogen atom is not in agreement with quantum mechanical model of an atom?AOption A. An atom in a stationary state does not emit electromagnetic radiation as long as it stays in the same state.BOption B. An atom can take only certain distinct energies E1E_1E1, E2E_2E2, E3E_3E3, etc. These allowed states of constant energy are called the stationary states of atom.COption C. The electron in a H atom's stationary state moves in a circle around the nucleus.DOption 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.CheckSkip · show solution
