Alpha-Particle Scattering and Rutherford's Nuclear Model of Atom

Answer the following question, which helps you understand the difference between Thomson’s model and Rutherford’s model better.

In which model is it completely wrong to ignore multiple scattering for the calculation of average angle of scattering of $\alpha -$ particles by a thin foil?

Answer the following question, which helps you understand the difference between Thomson’s model and Rutherford’s model better.

Keeping other factors fixed, it is found experimentally that for small thickness $t$, the number of  $\alpha$-particles scattered at moderate angles is proportional to $t$. What clue does this linear dependence on $t$ provide?

Answer the following question, which helps you understand the difference between Thomson’s model and Rutherford’s model better.

Is the probability of backward scattering (i.e., scattering of $\alpha -$ particles at angles greater than $90°$) predicted by Thomson’s model much less, about the same, or much greater than that predicted by Rutherford’s model?

Answer the following question, which helps you understand the difference between Thomson’s model and Rutherford’s model better.

Is the average angle of deflection of $\alpha -$ particles by a thin gold foil predicted by Thomson’s model much less, about the same, or much greater than that predicted by Rutherford’s model?

Suppose you are given a chance to repeat the alpha-particle scattering experiment using a thin sheet of solid hydrogen in place of the gold foil. (Hydrogen is a solid at temperatures below $14 \mathrm{K}$.) What results do you expect?
