The positively charged nucleus caused deflection. Positive charge is because of protons inside nucleus.
A zinc sulfide coated screen surrounding the gold foil produced a flash of light whenever it was struck by an alpha particle. By noting where the flash occurred, the scientists could determine if the atoms in the gold foil deflected the alpha particles.
positive
yes it was tested by the gold foil experiment
he shot tiny alpha particles throug a piece of gold foil. -Apex

That the mass of an atom is mostly located in a small nucleus.
The conclusion was that an atom has a nucleus (center) with a positive charge.
Rutherfords experiment proved the existence of a nucleus as some alpha particles "bounced back" from the gold foil sample . Thomson model did not involve a nucleus and predicted just a slight deflection or none at all.
For Rutherford's gold foil experiment, you will need the following materials: thin gold foil, alpha particles, a source for the alpha particles, a fluorescent screen or detector to observe the scattered particles, and a vacuum chamber to prevent air molecules from interfering with the experiment.
to find out if all element has the same mass or can pass through the tin foil in other words not all passed through
The purpose of the fluorescent screen in Rutherford's experiment was to detect the alpha particles that were deflected when they struck the gold foil. The screen would light up when hit by the alpha particles, allowing Rutherford to observe and measure the deflection pattern and infer the structure of the atom.
Everyone thought that the alpha particles would go through the gold- foil with little deflection. When the alpha particle passed straight through the gold atoms with no deflection or bounced straight back a small fraction bounced off at a large angle, or bounced straight back to the source. Rutherford came up with a new theory of the atom, that the atom is mostly empty space and in the center there is a nucleus. this is known as the nucleus atom.
