Answer the following questions, which help you understand the difference between Thomson's model and Rutherford's model better.
Is the average angle of deflection of α-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?

Solution

The average angle of deflection of

α

-particles by a thin gold foil predicted by Thomson's model is about the same as predicted by Rutherford.
