Question

Which of the following is not a drawback of Ruther-ford atomic model?

• A. It failed to explain why electrons just simply fall into the nucleus.
• B. It failed to explain why an atom emits discrat spectrum.
• C. It failed to explain why only a very small amount of $\alpha$ paticles get scattered.
• D. none of these

Answer 1

The correct option is C It failed to explain why only a very small amount of $\alpha$ paticles get scattered.

Model of the structure of atom had been first proposed by J. J Thomson. In his alpha ray scattering experiment it is observed that most of the alpha particles are undeflected, few particles are slightly deflected and few particles bounce of nucleus. But he failed to explain the reason for the scattering of these few alpha particles. This is a drawback of the Rutherford's atomic model.
