Structure of the Atom — Question 4

If the ∝–particle scattering experiment is carried out using a foil of a metal (as thin as gold) other than gold, then also the observation would be same because the structure of an atom, when considered individually is same.

However, other metals are not as malleable as gold so it is difficult to turn those metals into such thin sheets. If thick foil is used then it will result in the change of scattering angles which might affect the predictions of the experiment.
