Most of the particles went through the gold foil, but only a few bounced back.
What else can I help you with?
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 Ernest Rutherford know that atoms was mostly empty space?
> because he is smart lol TROLL
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.
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 Rutherford's gold-foil experiment help him conclude?
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.
What are facts about ernest Rutherford?
gold foil experiment and know to split an atom
What facts about Ernest Rutherford?

How do you know most of the mass of an atom is located in the nucleus?
the experiments of Ernest Rutherford in 1910

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 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.
The term rutherford gave to the positively charged particles in the nucleus of an atom was?
You should know this...Protons. Next time, just think about the question! (:
