Which of the following conclusions couldnot be derived from Rutehrford's `alpha`-particle scattering experiment?

Options

A. Most of the space in the atom is empty
B. The radius of the atom is about m `10^(-10)`m while that of nucleus is m `10^(-15)`m
C. Electrons move in a circular path of fixed energy called orbits
D. Electrons and the nucleus are held together by electrostatic forces of attraction

Answer

C

Explanation

Concept of electrons move in a circular path of fixed energy called orbits was put forward by Bohr and not derived from Rutherford’s scattering experiment.
Out of a large number of circular orbits theoretically possible around the nucleus, the electron revolves only in those orbits which have a value of energy. Hence, these orbits are called energy level or stationary states.
