Question

What do you think would be at the observation if the $straight alpha$ -particle scattering experiment is carried out using a foil of a metal other than gold?

Solution

If the $straight alpha$ scattering is carried out out using a foil of a metal rather than gold, there would be no change in the observation. In the α-scattering experiment, a gold foil was taken because gold is malleable and a thin foil of gold can be easily made. It is difficult to make such foils from other metals.
