In Rutherford's gold foil experiment most of the `alpha`-particles pass through the gold foil without any deviation from their paths . This indicates that

A

the atom is spherical

B

there is a positively charged nucleus at the centre of the atom

C

the entire mass of the atom is concentrated at the nucleus of the atom

D

most portion of the atom is empty space.

Text Solution

Verified by Experts

The correct Answer is:
D
Most of `alpha-` particles passed straight through the foil without suffering any deflection. This showed that most of the space inside the atom is empty.
