Particles fired at gold foil some going straight through?
The observation that some particles fired at gold foil went straight through indicated that the majority of the atom is empty space. This led to the discovery of the nucleus by Ernest Rutherford, who proposed the nuclear model of the atom.
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.
In Rutherford's gold foil experiment what particles were fired at a thin piece of gold?
I believe they are called the Alpha particles and yes, they did pass through a sheet of gold foil.
The kind of particle Rutherford used to shoot through gold foil?
Rutherford shot high-energy alpha particles (two protons and two neutrons, or a helium nucleus) at the gold foil. A small fraction of these alpha particles bounced back, and that is how Rutherford discovered the nucleus.
What happened to the alpha particles as they hit he gold foil?
When alpha particles hit the gold foil in the famous Rutherford experiment, most of them passed straight through, while a few were deflected at large angles, indicating that the atom was mostly empty space with a dense positively charged nucleus. This unexpected result led to the discovery of the atomic nucleus.
What did Rutherford observed that surprise him?
Most of the alpha particles shot at the gold foil went straight through the foil.
When Rutherford performed his metal foil experiment did the alpha particles pass straight through the foil or bounce back?
In Rutherford's metal foil experiment, some alpha particles passed straight through the foil, while others were deflected at various angles. A small fraction of the alpha particles even bounced back towards the source. This led Rutherford to conclude that atoms have a small, dense nucleus at their center.

In Rutherfords gold foil experiment particles in dense atomic nuclei caused some alpha particles to bounce straight back from the gold foil.?
positive
If Rutherford made bombarded aluminum foil with alpha particles instead of gold foil what observations would he have used?
The scattering angles would have changed, but the qualitative results would also change: the reason Rutherford chose gold was because it is EXTREMELY malleable. One can stretch gold foil until it is only a few atoms thick in places, which is not possible with aluminum. If the foil were too thick, there would be no transmission of particles at all; the whole point was to demonstrate that most alpha particles passed through unchanged, but some of them scattered, which is only possible with a VERY thin foil.
The gold foil experiment led to the conclusion that each atom in the foil was composed mostly of empty space because most alpha particles directed at the foil?
Most alpha particles passed straight through the foil, suggesting that atoms are mostly empty space. Some alpha particles were deflected at small angles, indicating the presence of a small, dense nucleus. A few were even reflected back, showing that the nucleus is positively charged.
How did the results of Rutherfords gold foil experiment differ from his expectations?
Everyone thought that the alpha particles would go through the gold- foil with little deflection. When the alpha particle passed straight through the gold atoms with no deflection or bounced straight back a small fraction bounced off at a large angle, or bounced straight back to the source. Rutherford came up with a new theory of the atom, that the atom is mostly empty space and in the center there is a nucleus. this is known as the nucleus atom.
What are the main ideas of e Rutherford gold foil experiment?
basically, Rutherford shot postively charged particles at a thin sheet of gold foil. most of the particles passed straight through, but some bounced off at sharp angles. This implies that most of the atom is empy space (which is why most of the particles go straight throught) , but there is a positively charged nucleus at the center (which repels the postively charged particles, so if a particle hits the nucleus, it bounces off )
What would have happend in the gold foil experiment if daltons theory had been correct?
If Dalton's theory had been correct in the gold foil experiment, all the alpha particles would have passed straight through the gold foil with little to no deflection. Dalton's theory proposed that atoms were indivisible and uniform in structure, so there would have been no interactions with the densely packed positive nucleus within the gold atoms.
Where did most of the alpha particles fired at the foil go in the gold foil experiment?
Most of them went right through.
What feature of rutherfords gold foil expirement was most surprising to those who carried out the expirement?
Some alpha particles deflected, some went straight through and come were deflected.
