Question

A small positively charged nucleus is present in the center. Which observations tells about this?

• A. Most of the $\alpha -$ particles passed straight
• B. Most of the $\alpha -$ particles rebounded after hitting the atoms
• C. Only a few $\alpha -$ particles deflected away from their path
• D. Very few $\alpha -$ particles rebounded

Answer 1

Answer: (C), (D)

The correct options are
C Only a few $\alpha -$ particles deflected away from their path
D Very few $\alpha -$ particles rebounded

The observations of $\alpha -$ ray scattering experiment lead to the presence of small positively charged nucleus in the centre.

Hence,
(i) Only a few $\alpha$ - particles deflected away from their path.
(ii) Very few $\alpha$ - particles rebounded.
