Rutherford's experiment on scattering of...

Rutherford's experiment on scattering of alpha particles showed for the first time that atom has :

A

Electron

B

Proton

C

nucleus

D

Neutrons

Text Solution

Verified by Experts

The correct Answer is:
C
According to the conclasions of Ratherford's `alpha` scattering experiment m ost of the atom is empty So, the `alpha` particle go across undefiected .The positive charge is concetrated is a very small space in the atom, which deflected the posivelity charged `alpha` particle .This small and particle that happen to travel in line with the nucleus get deflected by `180^(@)`
