Question:

What is correct relation between the volume of nucleus and that of an atom ?

Options:

The volume of a nucleus is about 10–15 times the volume of the atom.

The volume of a atom is about 10–12 times the volume of the nucleus.

The volume of a nucleus is about 10–12 times the volume of the atom.

The volume of a atom is about 10–15 times the volume of the nucleus.

Correct Answer:

The volume of a nucleus is about 10–12 times the volume of the atom.

Explanation:

Experiments on scattering of α-particles demonstrated that the radius of a nucleus was smaller than the radius of an atom by a factor of about 104 . This means the volume of a nucleus is about 10–12 times the volume of the atom.
