There is a solid region in the atom, he named this part of atom as Nucleus.
The alpha particules went straight threw the gold foil
Rutherford's gold foil experiment did not discover the existence of any subatomic particles, but it did show the existence of a small, tightly packed, positively charged nucleus and thus led to the discovery of protons.
Rutherford was a scientist who shot alpha particles through a very thin sheet of gold foil. The results of this experiment are the following: -Almost all alpha particles passed right through the Gold foil -A few alpha particlas were deflected and repelled .....These conclusions show that the majority of the atom of gold is empty space except for a small, positively charged nucleus. This nucleus is the reason why some alpha particlas were deflected(Alpha particles have a positive charge, which is repelled by a positive nucleus).
Ernest did an experiment where he shot alpha particles into a gold foil that proved the concept of a nuclear atom, that is an atom with a nucleus made of protons and neutrons and have electrons moving around the nucleus in some way. His experiment did not show the position of electrons or energy levels or even how they moved.
A diagram of the Geiger-Marsden (aka gold foil) experiment? Why yes, there is. A link is provided to a simple diagram. It should be mentioned that the "scintillation screen" where the interactions occurred that produced the little blink of light was a film on the curved strip that surrounded the experiment. All the little dots of light had to be observed by an experimentalist. No detectors, no electronics, no computers, no nothin'. Just simple, smart experimental activity that had everything to do with the labor of intense observation over an extended period. Gotta love they guys who did it. And we name the experiment after them. Notice that it is the Geiger-Marsden experiment. These two cats were Rutherford's assistants, and they did all the work. We gotta give 'em their props.
The gold foil experiment demonstrated this.
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.

This classic diffraction experiment was conducted in 1911.

The gold foil experiment showed that there is a nucleus by how the alpha particles(positively charged particles) were deflected and changed course by the foil. It showed that the atom is made of mostly empty space because most particles went through the foil. Some of the particles though were deflected to the sides of the container around the foil and some where even reflected back at the light almost. Rethurford (or however you spell is name lol search it) theorized that there is a small nucleus that is positively charged that some particles came close to and were deflected away because the nucleus had an effect on them. Some particles hit the nucleus exactly and were reflected back only because it was positively charged if it had been negativly charged it wouldn't have went back to the light.
The experiment you're asking about was performed by Ernest Rutherford, and it's one of the most important experiments in our quest to understand the nature of atoms. We call this experiment the gold foil experiment. What Rutherford did was shoot alpha particles, which are just charged helium atoms, at thin gold foil. Most of the alpha particles passed right through the gold foil. Some of the particles would deflect by a small angle. Occasionally, though, some of the particles would shoot back at the alpha emitter or off at a sharp angle. Before this experiment one of the more popular atomic models was the "plum pudding" model. This model said that protons and electrons filled up all the space of the atom equally. We know now, and because of this experiment, that protons are located at the very center of an atom and they take up very little space. If the plum pudding model were correct you would expect the particles to all act the same; either all of them would be reflected in the same direction or all of them would pass through. But, if the protons were all tightly packed in the center you would expect most of the alpha particles to pass straight through the gold foil because they are just passing through empty space. Occasionally one might get close and be deflected a little bit. Even more rarely you would expect to see some of the alpha particles shoot right back at you. These are exactly the results you see from the gold foil experiment and they show us that atoms are mostly empty space.
