Most of his test particles (alpha particles) when straight through.
The Nuclear Model-1909 Ernest Rutherford's great contribution to atomic theory was to show what happens to an element during radioactive decay. This enabled him to construct the first nuclear model of the atom, a cornerstone of present-day physics The Nuclear Model-1909 Ernest Rutherford's great contribution to atomic theory was to show what happens to an element during radioactive decay.

The conclusions of the gold foil experiment were that atoms are mostly empty space with a small, dense nucleus at the center. This led to the development of the nuclear model of the atom. Drawbacks of the experiment include the assumption that all alpha particles would be deflected, which was not always the case, and the limited precision of the equipment used at the time.
positive
Rutherford compared an atom to a solar system. But this would mean that as the electrons rotate they radiate energy and as they do so the radius of their path would keep on decreasing and would ultimately collide with the nucleus and the atom would be destroyed. but we know that this does not happen. Bohr on the other hand stated that the electrons rotate in specific orbits.
dense
Rutherford's key discovery was that the atom has a small, positively charged nucleus and is mostly empty space. Thomson discovered the electron and proposed the "plum pudding" model of the atom, in which electrons were embedded in a positively charged sphere.
> because he is smart lol TROLL
Rutherford Discovered Many key factors of the atom. Especially about Protons and Electrons. He Did Not Know about neutrons. He Concluded That The atoms electron cloud was positive and electron floated around it like chocolate chips in a cookie.
Most of the particles went through the gold foil, but only a few bounced back.

When Rutherford put the gold foil in front of the alpha-particle emitting source, he noticed a few things: 1. Some of the alpha particles passed through the gold foil 2. Some the particles were deflected 3. Some of the particles bounced back Rutherford concluded that an atom is made up of mostly empty space and the actual size of the atom is far smaller than the space it occupies.

The electrons are repelled by the protons, which causes then to be farther away. If the nucleus was the size of a marble, then the atom would be the size of a football stadium. Correction: Electrons are not repelled by the protons but are attracted to them. Opposite charges attract.
Geiger and Marsden, under Rutherford's direction, fired alpha particles at a very thin sheet of gold foil. They used a movable fluorescent screen to determine where the alpha particles went after passing through the foil. The screen emitted tiny flashes of light whenever an alpha particle struck it, so Rutherford and his team could see how the particles were being affected by the atoms they struck. Based on Thomson's model of the atom as a diffuse sphere of intermeshed positive and negative charge, Rutherford expected all of the alpha particles to pass through the gold foil with little or no scattering; indeed, they found that most of the particles passed straight through the foil, as if it weren't even there. In other words, the greatest number of flashes occurred when the screen was held directly behind the gold foil, in the path of the alpha particles. A tiny fraction of the particles, however, were reflected back toward the alpha emitter. From this Rutherford concluded that gold atoms must be mostly empty space, with tiny, dense, positively charged nuclei surrounded by extremely rarefied clouds of negative charge.
You should know this...Protons. Next time, just think about the question! (:
