When alpha particle are sent through a thin metal foil ,most of them go straight through the foil because

A

`alpha`-particles are much heavier than electron

B

`alpha`-particles are positively charged

C

`alpha`-particles move with high velocity

D

most part of the atom is empty

Text Solution

Verified by Experts

The correct Answer is:
