Ernest Rutherford is the scientist who discovered the nucleus through his gold foil experiment in 1909. He observed that most of the alpha particles passed through the foil, but some were deflected, leading him to propose the existence of a dense, positively charged nucleus at the center of an atom.
Faraday's experiment with electrolysis provided clues about the existence of electrons. He observed that when an electric current passed through an electrolyte solution, elements were deposited at the electrodes in specific ratios, indicating the presence of fundamental particles carrying electric charge.
Rutherford discovered that atoms are mostly empty space through his famous gold foil experiment. He observed that most of the alpha particles passed straight through the foil, indicating that atoms had a lot of empty space. The few particles that were deflected showed that the positive charge in an atom is concentrated in a small nucleus at the center.
The conclusion was that the nucleus of an atom is small, dense, and positively charged, as most of the alpha particles passed through the gold foil with a minor deflection, indicating that the majority of the atom is empty space. This led to the development of the nuclear model of the atom.

to find out if all element has the same mass or can pass through the tin foil in other words not all passed through
Gold was chosen for Rutherford's experiment because it is a malleable metal that can be made into extremely thin foils, allowing alpha particles to be passed through easily. Additionally, gold atoms have a high atomic number which results in a denser concentration of positive charge in the nucleus, making it ideal for studying the structure of atoms.
Rutherford's gold foil experiment showed that atoms have a small, dense positively charged nucleus at their center, with most of the atom consisting of empty space. This led to the development of the nuclear model of the atom, where electrons orbit the nucleus. The experiment also suggested that the positive charge of the nucleus is concentrated in a small volume, explaining why most alpha particles passed through the foil undeflected.
In the gold foil experiment by Rutherford, most alpha particles passed through the gold foil, indicating that atoms are mostly empty space. The few particles that were deflected showed that the positive charge of the atom is concentrated in a small, dense nucleus, which explains why most of the particles passed through without being deflected.
In Rutherford's metal foil experiment, some alpha particles passed straight through the foil, while others were deflected at various angles. A small fraction of the alpha particles even bounced back towards the source. This led Rutherford to conclude that atoms have a small, dense nucleus at their center.

Rutherford was expecting the result to be what JJ Thomson had predicted. That the Alpha Particles just pass through the gold foil, not rebound, like the result. JJ Thomson thought of this result because of his plum pudding model.

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.
