If the alpha particles hit the gold foil most of the alpha particles will pass through the gold foil because atoms mostly consists of empty space and some alpha particles will be deflected including a very small number of alpha particles will bounce back in the direction they came from because the atom has a very small positively charged mass called the nucleus.
most pass straight through with no deflection, the next largest amount bounce right back the way they came with nearly 180º deflection, a small number pass through with a tiny deflection of a few degrees.
Alpha particles are scaterred by the atomic nucleus.

The scattering angles would have changed, but the qualitative results would also change: the reason Rutherford chose gold was because it is EXTREMELY malleable. One can stretch gold foil until it is only a few atoms thick in places, which is not possible with aluminum. If the foil were too thick, there would be no transmission of particles at all; the whole point was to demonstrate that most alpha particles passed through unchanged, but some of them scattered, which is only possible with a VERY thin foil.
Only a small percentage of alpha particles shot at the gold foil were deflected proving that except for the nucleus, the atom was mostly empty space.
The scattering of alpha particles by a metal foil.
Yes, that is true. In the Rutherford gold foil experiment, some alpha particles were observed to bounce off the gold foil because they came close to or hit the positive protons present in the nucleus of gold atoms. This result led to the discovery of the atomic nucleus and the understanding that atoms are mostly empty space.
Rutherford shot beta particles at gold foil to discover protons, but i have never heard of an aluminum foil experiment.
The beta particles permeated the gold foil. Permeated means "penetrated something"
I believe they are called the Alpha particles and yes, they did pass through a sheet of gold foil.
Rutherford by bombarding gold foil with positively charged particles and noting that some particles were widely deflected.
Hi I believe the answer to be because of its high density. Gold or Aurum (Au) is very dense and hence will 'reflect'and 'deflect' alpha particles, which are helium nuclei. Beta particles are electrons Hope that helps

never heard of Rutherford famous gold foil experiment?
If he used magnesium, the alpha particles would have passed though
atoms
They traveled through the empty spaces of the gold foil.
