(i) Most of the space in the atom is empty.
(ii) The radius of the atom is about 10–10 m while that of a nucleus is 10–15 m.
(iii) Electrons move in a circular path of fixed energy called orbits.
(iv) Electrons and the nucleus are held together by electrostatic forces of attraction.
Correct Answer: (iii) Electrons move in a circular path of fixed energy called orbits
Explanation: The conclusion of Rutherford’s α -particle scattering experiment do not describe that the electrons move in a circular path of fixed energy called orbits.
