Question
Write two important limitations of Rutherford nuclear model of the atom.

Answer

  1. According to Rutherford model, electron orbiting around the nucleus, continuously radiates energy due to the acceleration; hence the atom will not remain stable.
  2. As electron spirals inwards; its angular velocity and frequency change continuously; therefore it will emit a continuous spectrum.
