The correct answer should be a he told them that there can be other elements that would be in the world.
Yes , Rutherford's gold foil experiment was about the atomic structure. He bombarded 8000 alpha particles on the gold foil and the source of alpha particle was POLONIUM (an element in periodic table). After bombarding rays, he observed that most of the rays passed without deflecting, and few rays deflected backward. By this , he concluded that most part of the atom is empty. That empty part is also called extra nuclear part or energy levels, shells or orbit . Nucleus lies in the centre of the atom which carries positive charge. It was his assumption which was right. Because two like charges always repel each other. since alpha particles carries positive charge and it can repeled by only positive charge.
Electrons revolve in extra nuclear part.One thing that was wrong about Rutherford experiment was his assumption that eletron while revolving in the extra nuclear part continuously radiate energy.
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.
According to Thomson's atomic theory, the mass of an atom was special evenly throughout its volume. Errest Rutherford's experiment proved this wrong.

Probable you think to the Rutherford experiment.
Geiger and Marsden's gold foil experiment provided evidence for the existence of a dense nucleus at the center of an atom, based on the unexpected deflections of alpha particles being scattered at large angles. This supported the model proposed by Ernest Rutherford, which revolutionized atomic theory by introducing the concept of a small, positively charged nucleus surrounded by negatively charged electrons.
positive
The positively charged nucleus caused deflection. Positive charge is because of protons inside nucleus.
Ernest Rutherford's famous "gold foil" experiment changed the way we though of atomic structure. His demonstration proved that atoms have a small, dense nucleus which contains protons and neutrons. The electrons were shown to be outside the nucleus. Prior to this, we thought atoms had a consistent structure throughout, like soup or pudding.
Because Joel is the man
no
The Rutherford scattering experiments validated the presence of a small, dense, positively charged nucleus at the center of the atom. They also confirmed that most of the atom's mass is concentrated in the nucleus. Additionally, the experiments revealed that electrons orbit the nucleus at a distance, debunking the earlier "plum pudding" model of the atom.
The scientist who first postulated the theory of atomic structure was John Dalton. He proposed his atomic theory in the early 19th century, suggesting that elements are composed of indivisible particles called atoms.
