Question

Which of the following conclusions could not be derived from rutherford’s $\alpha$ - particle scattering experiment?

• A. Most of the space in the atom is empty.
• B. The radius of the atom is about $10^{- 10}$ m while that of nucleus is $10^{- 15}$ 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 1

Answer: (C)

Electrons move in a circular path of fixed energy called orbits.

Answer 2

: The conclusion “Electrons move in a circular path of fixed energy called orbits” was given by Bohr’s model, not by Rutherford’s $\alpha$ - particle scattering experiment.
