Question

Alpha particles beamed at thin metal foil may a. pass directly through without changing direction b. be slightly diverted by attraction to electrons c. be reflected by direct contact with nuclei d. A and C e. A, B, and C

Answer 1

Answer:

The correct option is E.

Explanation:

When alpha particles beamed at thin metal foil that time most of the particles of alpha pass through the foil with no deflection. This observation defined about two statements:

1) The diameter of the atom compared with the diameter of the nucleus.

2) The mass of an atom compared with the mass of the nucleus.

So, the correct options are:

A: Pass directly through without changing direction.

B: Be slightly diverted by attraction to electrons.

C: Be reflected by direct contact with nuclei.
