Rutherford's alpha-particle scattering experiment discovered

A

mass and energy are related

B

electrons occupy space around the nucleus

C

neutrons are burried deep in the nucleus

D

the point of impact with matter can be precisely determined

Text Solution

Verified by Experts

The correct Answer is:
B
According to Rutherford’s model, there is a heavily positively charged nucleus and negatively charged electrons occupy space around it in order to maintain electro-neutrality.
