Choose the correct option from the following options given below :

Option: 1

In the ground state of Rutherford's model electrons are in stable equilibrium. While in Thomson's model electrons always experience a net-force.


Option: 2

An atom has a nearly continuous mass distribution in a Rutherford's model but has a highly non-uniform mass distribution in 'Thomson's model


Option: 3

A classical atom based on Rutherford's model is doomed to collapse.


Option: 4

The positively charged part of the atom possesses most of the mass in Rutherford's model but not in Thomson's model.

\rightarrow Rutherford's performed \alpha - particle scattering experiment

\rightarrow 1 out of 20000 \alpha - particle had scattering angle equal to 180^{\circ}

\rightarrow Scattering of 180^{\circ} is possible only when the mass is concentrated somewhere

\rightarrow So, in the model he proposed that the positively changed part of the atom passesses most of the mass.

The correct option is (D)
