Structure of Atom question

2025 · 3 Apr · Shift 1 · Q5

JEE MainChemistryStructure of AtomMCQ+4 / −1
Which of the following postulate of Bohr's model of hydrogen atom is not in agreement with quantum mechanical model of an atom?
  1. A
    The electron in a H atom's stationary state moves in a circle around the nucleus.
  2. B
    An atom can take only certain distinct energies E1,E2,E3\mathrm{E}_1, \mathrm{E}_2, \mathrm{E}_3E1​,E2​,E3​, etc. These allowed states of constant energy are called the stationary states of atom.
  3. C
    An atom in a stationary state does not emit electromagnetic radiation as long as it stays in the same state.
  4. 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.
