When atoms are bombarded with alpha particles, only a few in millon suffer deflection, other pass out undeflected. This is because.

A

The force of repulsion on the moving alpha particle is small

B

The force of attraction on the alpha particle to the oppositely charged electrons is very small

C

There is only one nucleus and large number of electrons

D

The nucleus occupies much smaller volume compared to the volume of the atom.

Text Solution

Verified by Experts
