Solution

The correct option is D
Gold can be easily hammered into a thin layer of 1000 atoms without breaking it and also does not chemically react with alpha particle.

Rutherford selected a gold foil because gold is most malleable metal i.e gold can be beaten up into a thin layer of 1000 atoms without cracking or breaking. And gold does not absorb or chemically react with alpha particle.

But, on the other hand gold is very rare and relatively expensive to produce.

Gold does not react easily with acid but it reacts with aqua regia. What is aqua regia ? Why does it react with gold?

Ernest Rutherford made the alpha particles to fall on the thin gold foil. So, most of the alpha particle travelled through the gold foil peircing it or not?

I

. During Rutherford's gold foil experiment, a beam of alpha particles was directed at a thin sheet of gold foil. This helped to prove the existence of a nucleus in the atom.

I I

. Most of the positively charged alpha particles were able to pass undeflected through the gold foil.

Why did Rutherford select a gold foil in his $α$ -particle scattering experiment?
