Text Solution

Verified by Experts
The correct answer is:
A

The positive charge is concentrated in a very small volume of the atom.
Very few bombarded -particles on gold foil were deflected by sharp angles and therefore, it was concluded that the positive charge is concentrated in a very small volume of the atom called a nucleus. Since few were deflected, the size of the nucleus is very small as compared with atom size.
