Which of the following is a drawback of Rutherford model?

The correct option is C Both A and B
The major drawback of Rutherford experiment is that the orbital revolution of the electron is not expected to be stable. According to Rutherford's model, the electrons, while moving in their orbits, would give up energy. This would make them slow down, gradually and move towards the nucleus. The electrons will follow a spiral path and then fall into the nucleus. Ultimately, the atom would collapse. But in reality the atom is stable.
