Question
Which of the following conclusions could not be derived from Rutherford’s α -particle scattering experiment?
Options
Most of the space in the atom is empty.
The radius of the atom is about 10–10 m while that of nucleus is 10–15 m
Electrons move in a circular path of fixed energy called orbits.
Electrons and the nucleus are held together by electrostatic forces of attraction.

Solution
Electrons move in a circular path of fixed energy called orbits.
Explanation:
As per Rutherford’s α-particle scattering experiment the nucleus is surrounded by electrons that move around the nucleus with a very high speed in circular paths called orbits. It does not mention the energy or stability of the electrons revolving around the nucleus.
