Question

Will rutherford’s experiment change if thicker gold foil was used

Answer 1

Yes, Rutherford's experiment showed that atoms consisted of a dense mass which was surrounded by mostly empty space - the nucleus! Rutherford's experiment utilized positively charged alpha particles (He with a +2 charge) which were deflected by the dense inner mass (nucleus).

Answer 2

Explanation:

The breaking angles would have changed, but the qualitative results would also change: the reason Rutherford chose gold was that it is notably flexible One can spread gold foil until it is only a few atoms wide in places, which is not achievable with aluminum.
