Solution

The correct option is D All are correct
On the basis of the atomic model Rutherford concluded that :
(A) atoms consist of predominantly empty spaces
(B) atoms consist of central, tiny nucleus containing positively charged particles.
(C) Whole of the atomic mass is concentrated in the nucleus
Also, positive charge is concentrated in the nucleus. He also concluded that the number of positively charged particles in an atom is exactly equal to the number of extra-nuclear electrons. So an atom is electrically neutral.

Which of the following conclusions can be drawn from the Rutherford alpha scattering model?

I. The atom is mostly empty space.
II. Electrons orbit the nucleus of the atom.
III. The atom has a dense, positively charged nucleus.

During Rutherford's α-particle scattering experiment, he concluded that:

(i) electrons have a negative charge.
(ii) the mass and positive charge of the atom is concentrated in the nucleus.
(iii) neutron exists in the nucleus.
(iv) most of the space in an atom is empty.

Statement I- Thomson's atomic model could not explain the result of scattering experiment performed by Rutherford.
Statement II- According to Rutherford, majority of mass was concentrated in a minute, positively charged region (the nucleus) surrounded by electrons.
