Bohr's atom model assumes

Options

  1. Athe nucleus is of infinite mass and is at rest
  2. Belectrons in a quantised orbit will not radiate energy
  3. Cmass of the electron remains constant
  4. DAll of the above

Correct answer

D. All of the above

Step-by-step solution

Bohr assumed one of the postulates of Rutherford's atomic model. That is the mass of the nucleus is very large compared to that of the electrons and hence assumed to be infinite. Electrons in quantised orbit does not radiate energy. Mass of electron remains constant.
