Question:

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

Answer:

Thin gold sheets are used because gold has the highest malleability and it does not react with a-particles. So other than gold, a-particles scattering is also possible with the foil of other metal which is malleable and does not react with a-particles like silver, platinum, copper, etc.
