A beam of alpha particles shot through a thin thin thin gold foil will occasionally have a few coming close to the nucleus of a gold atom - and as alpha particles have the same charge as the nucleus there is a repulsive force, which forces the particle from its original course. To keep a graduate student busy (I believe it was Marsden) Rutherford asked him to investigate if there was any particles that got deflect through an angle larger than 90'. (A preposterous notion) An to his great surprise there was.

What experiment convinced Ernest Rutherford thet atom has a small positively charged nucleus?
The gold foil experiment convinced Ernest Rutherford that the atom has a small positively charged nucleus. In this experiment, alpha particles were shot at a thin gold foil. The fact that some of the alpha particles were deflected and even bounced back led Rutherford to conclude that atoms have a small, dense, positively charged nucleus.
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.
What feature of rutherfords gold foil experiment was most surprising to those who carried out the experiment?
The most surprising feature of Rutherford's gold foil experiment was the discovery that some alpha particles were scattered at very large angles, even back towards the source. This suggested that the positive charge in an atom was concentrated in a small, dense nucleus, rather than being spread out as previously thought.
In Rutherford's gold foil experiment particles in dense atomic nuclei caused some alpha particles to bounce straight back from the gold foil.?
positive
In Rutherford's gold experiment particles in dense atomic nuclei caused some alpha particles to bounce straight back from the gold foil?
Yes, in Rutherford's gold foil experiment, he observed that some alpha particles were deflected at very large angles and even bounced straight back, indicating that they were hitting something small and dense (the atomic nucleus) within the gold foil. This observation led to the development of the nuclear model of the atom.
What is the main observation of the Rutherford's experiment?
Most of the particles went through the foil, but some were deflected
Who discovered the nucleus using his gold foil experiment?
Ernest Rutherford is the scientist who discovered the nucleus through his gold foil experiment in 1909. He observed that most of the alpha particles passed through the foil, but some were deflected, leading him to propose the existence of a dense, positively charged nucleus at the center of an atom.
What experiment convinced Ernest Rutherford thet atom has a small positively charged nucleus?
The gold foil experiment convinced Ernest Rutherford that the atom has a small positively charged nucleus. In this experiment, alpha particles were shot at a thin gold foil. The fact that some of the alpha particles were deflected and even bounced back led Rutherford to conclude that atoms have a small, dense, positively charged nucleus.
How was Rutherford theory proven?
Rutherford's theory that atoms have a small, positively charged nucleus was proven through the famous gold foil experiment. In this experiment, alpha particles were shot at a thin gold foil, and some particles were deflected back, suggesting a small, dense nucleus within the atom. This experiment provided strong evidence for the nuclear model of the atom.
What is the explanation for the scattering experiment of Rutherford?
Rutherford conducted an experiment in which Alpha particles were fired at a gold nucleus. Most of the particles passed through unaffected. However, some were deflected by a small amount whilst an even smaller number of the particles were deflected completely. This led to the conclusion that the atom has an extremely small, central, positively charged nucleus. As both the positive alpha particle and the positive nucleus repel each other by electrostatic forces. The fact that only a small amount of particles are deflected shows that the nucleus is only a tiny central part of the atom.
How is Thomson's model based on the experiment of passing alpha particles through the gold foil?
The results of this experiment led to the model of the atom called "Rutherford's model", rather than Thomson's model, which it basically disproved. Some of the alpha particles were deflected in ways that suggested to Rutherford that most of the atom's mass was concentrated in a positively charged "nucleus".
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.
What is the gold leaf experiment?
The gold leaf experiment was a famous experiment conducted by Ernest Rutherford in 1909 to study the structure of the atom. He bombarded a thin piece of gold foil with alpha particles and observed that some particles were deflected, indicating that atoms have a dense, positively charged nucleus at their center. This experiment led to the development of the nuclear model of the atom.
What feature of rutherfords gold foil experiment was most surprising to those who carried out the experiment?
The most surprising feature of Rutherford's gold foil experiment was the discovery that some alpha particles were scattered at very large angles, even back towards the source. This suggested that the positive charge in an atom was concentrated in a small, dense nucleus, rather than being spread out as previously thought.
Who discovered the nucleus using his gold foil?
Rutherford by bombarding gold foil with positively charged particles and noting that some particles were widely deflected.
In Rutherford's gold foil experiment particles in dense atomic nuclei caused some alpha particles to bounce straight back from the gold foil.?
positive
In Rutherford's gold experiment particles in dense atomic nuclei caused some alpha particles to bounce straight back from the gold foil?
Yes, in Rutherford's gold foil experiment, he observed that some alpha particles were deflected at very large angles and even bounced straight back, indicating that they were hitting something small and dense (the atomic nucleus) within the gold foil. This observation led to the development of the nuclear model of the atom.
