Explanation:

• Geirger and Marsden (students of Rutherford) studied the scattering of alpha particles by gold foil on the advice of Rutherford and made the following conclusions :

1. mMost of the mass ( at least 99.95 % ) and all of the charge of an atom is concentrated in small region , that region is called as atomic nucleus .

2. Nucleus is positively charged and the nucleus occupies only about 10⁻¹² of the total volume of the atom or less.

3. In an atom there is a empty space which is maximum and revolve around the nucleus in the same way as the planets revolve around the sun.
