MCQ

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.

  Is there an error in this question or solution?
