When alpha particle are sent through a ...

When alpha particle are sent through a thin metal foil ,most of them go straight through the foil because

A

`alpha-` particles are much heavier than electrons

B

`alpha-`particles are positively charged

C

Most part of the atom is empty space

D

`alpha-`particles move with high velocity

Text Solution

Verified by Experts

The correct Answer is:
C
If on moving in a straight line a charged particle shows that it is not influenced by any other particle in a wider range then we can conclude that most part in the atom is empty space. This also comes from Rutherford’s experiement that the atom has large empty space and that the nucleus occupies a very small part of the atom in terms of volume.

Assertion: In Rutherford's experiment, a-particles from a sodium source were allowed to fall on a 104 mm thick gold foil. Most of the particles passed straight through the foil. Reason : The entire positive charge and nearly whole of the mass of an atom is concentrated in the nucleus.
