First he took gold and made a sheet that was absurdly thin. Gold is soft and doesn't fall apart easily so it was ideal for this purpose.
Then he used a known method of producing alpha particles(which are actually nucleus's of helium we found out later), and shot them at the gold foil. in a nearly complete circle around the gold foil he had detectors for this "radiation" (he had an opening where the radiation gun was). nearly all of the "pellets" went straight through the foil without any damage to it or distortion to the particles. A few seemed to bounce off, as they were detected behind the foil and more or less random. He said that this rebound was like a 6 inch artillery shell being fired at a sheet of tissue paper and for it to come straight back.
He then put forward the idea of nucleus's and empty space 'as the fly in the cathedral' which overturned the previous nugget theories (and a bunch of others).
What else can I help you with?
What makes up most of the volume of an atom?
the electron cloud. some people say that's its mostly made up of "nothing" , but that is incorrect. it has to have SOMETHING in it or else it wouldn't be an atom, no? and yes i have done research on this, so i know that my answer is 100% accurate.
What did Rutherford infer as a result of his observations?
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.
What did Democritus conclude about atomic structure?
Democritus stated that if you cut a gold into its smallest piece a piece wherein it can't be cut anymore is what he called atomos. Which in Greek "A" means not and "TOMOS" means cut.
How would you describe the gold-foil experiment?
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.
How did Rutherford come to the conclusion that the space occupied by the nucleus is very small and the atom is almost all empty space?
Rutherford came to this conclusion after his Gold-Foil experiment. He found that most of the alpha particales(when released) went straight through the gold foil of which consisted of atoms. In the middle of the atom theres a small nucleus that has mass and positive charge. Because the nucleus is so small the alpha particles were able to go straight through leading to the conclusion that atoms are mostly empty space. so why did he do the gold-foil experiment?
How did Rutherford know an atom was mostly empty pace?
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.
How do you know that atom is mostly empty space?
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.
How did Ernest Rutherford know that atoms was mostly empty space?
> because he is smart lol TROLL
What is the homophone for no empty space?
dense
Does it make sense to say that a textbook is about 99.9 percent empty space?
No, it doesn't make sense to say that a textbook is about 99.9 percent empty space. A textbook is filled with information, illustrations, text, and other content, so it is not accurate to describe it as mostly empty space.
What were rutherford's and Thomson's key discoveries about the atom?
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.

How did Rutherford know that atom was mostly space?
Most of the particles went through the gold foil, but only a few bounced back.

What is one of Dalton's theories that has been disproved?
Dalton theorized that an atom was a tiny solid sphere. Today we know that atoms are not solid, in fact are mostly open space.
How did Rutherford's know that an alpha was mostly empty space?
most of the particles went through the gold foil, but only a few bounced back. answered by: Cherry Perez (Zamboanga City) ^______^
If there are the areas of 'nothingness' in outer space what actually is there?
These areas of "nothingness" are mostly empty space, with a few stray atoms and other particles. There is also evidence for something called dark energy, which is somehow connected to the expansion of space. Scientists still do no know what this dark energy is.
