प्रश्न

Which of the following conclusions could not be derived from Rutherford’s α -particle scattering experiment?

पर्याय

  • 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.

उत्तर

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.
