Question

Which of the following statements about Rutherford's model of an atom is not correct?

• A. Most of the atom's mass is concentrated in an extremely small region called nucleus
• B. Electrons move around the nucleus in orbits
• C. Electrons and nucleus are held together by electrostatic forces of attraction
• D. The model explained the stability of an atom

Answer 1

The correct option is D The model explained the stability of an atom

The Rutherford's model of atom failed to explain the stability of an atom. As an electron moves in a circular path, it should undergo acceleration and radiate energy. This would result in the electron losing energy continuously and eventually spiralling into the nucleus.
