Rutherford's `alpha` particle scattering experiment eventually led to the conclusion that

A

neutrons are buried deep in the nucleus

B

the point of impact with matter can be precisely determined

C

electrons occupy space around the nucleus

D

mass and energy are related

Text Solution

Verified by Experts

The correct Answer is:
C
Since majority of the `alpha` particles penetrated the metal foil undeflected, Rutherford proposed that most of the atoms must be empty space occupied by the lightweight electrons.
