In Geiger-Marsden experiment, it can be ...

In Geiger-Marsden experiment, it can be fairly assumed that the gold nucleus remains stationary throughout the scattering process as

A

gold foild is very thin

B

`alpha`-particles are moving very fast

C

`alpha`-particles carry positive charge

D

gold nucleus is about 50 times heavier then `alpha`-particles

Text Solution

Verified by Experts

The correct Answer is:
D
For gold, Z=79. since, the nucleus of gold is about 50 times heavier than an `alpha`-particle, it is reasonable to assume that it remains stationary throughout the scattering process.
