Question

Why did rutherford select a gold foil in his a-ray scaterring experiment?

Answer 1

Because it can be converted into very thin sheets so that very less nuclues were in between so many aplha particles can pass straight. If he would have chosen iron foil, alpha particle would moslty deflect

Answer 2

Rutherford used gold for his scattering experiment because gold is the most malleable metal and he wanted the thinnest layer as possible. The gold sheet used was around 1000 atoms thick. Therefore, Rutherford selected a Gold foil in his alpha scatttering experiment.
