Why did Rutherford select a gold foil in his `alpha`-ray scattering experiment ?

Rutherford's alpha-scattering experiment

Enlist the conclusions drawn by Rutherford from his alpha -ray scattering experiment.

Thickness of the foil of gold used in alpha -particle scattering experiment is

Very thin foil of gold was used in scattering experiment. Why ?

Rutherford's alpha-particle scattering experiment discovered

When a silver foil (Z = 47) was used in an alpha ray scattering experiment , the number of alpha -particles scattered at 30^(@) was found to be 200 per minute. If the silver foil is replaced by alumninium (z = 13) foil of same thickness, the number of alpha -particles scattered per minute at 30^(@) is nearly equal to

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

Number of the alpha - particle deflected in Rutherford's alpha -scattering experiment varies with the angle of deflection. Then the graph between the two is best represented by.
