Question

Why Alpha particle scattering experiment was possible by using gold foil only and not by foil of any other metal

Answer 1

HEYA!!
---------

↘Gold foil was used by Ernest Rutherford for his alpha particles scattering experiments as Gold is an un reactive ( noble metal ) . It is malleable and hence it's thin foil allowed easy deflection of the alpha particles.

This might not be possible with the other heavy as well as light metals .

Answer 2

☆$\red {HELLO\:DEAR}$☆

If the α-scattering experiment is carried 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.
