Question

Which of the following are the limitations of Rutherford’s experiment?
(i) Rutherford couldn't explain how many electrons rotate in a particular orbit.
(ii) Rutherford was not able to explain the stability of an atom.
(iii) Rutherford couldn't explain why electrons undergo acceleration and radiate energy.
(iv) Rutherford couldn't explain the presence of nucleus.

• A. Only (i), (ii) and (iii)
• B. Only (ii), (iii) and (iv)
• C. Only (i), (ii) and (iv)
• D. (i), (ii), (iii) and (iv)

Answer 1

The correct option is C

Only (i), (ii) and (iv)

The limitations of Rutherford’s experiment is that Rutherford could not explain how many electrons rotate in a particular orbit.It can be explained further that the revolution of the electron in a circular orbit is not expected to be stable.Any particle in a circular orbit would undergo acceleration,during acceleration, charged particles would radiate energy.Thus, the revolving electrons would lose energy and finally fall into nucleus. This means that the atoms are highly unstable, which is not true.
