Why did Thomson's model fail?

Is the size of the atom in Thomson's model is the same as the atomic size in Rutherford's model?

On the basis of Thomson's model of an atom explain how the atom is neutral as a whole.

What are the limitations of J.J. Thomson model of atom ?

Answer the following questions, which help you understand the difference b/w thomson's model and rutherford model: 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?

Answer the following questions which help you to 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 angle 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 help 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?
