The initial discovery of "Rutherford Scattering" was made by Hans Geiger and Ernest Marsden in 1909 when they performed the gold foil experiment under the direction of Rutherford, in which they fired a beam of alpha particles (helium nuclei) at layers of gold leaf only a few atoms thick. The intriguing results showed that around 1 in 8000 alpha particles were deflected by very large angles (over 90°), while the rest passed straight through with little or no deflection. From this, Rutherford concluded that the majority of the mass was concentrated in a minute, positively charged region (the nucleus) surrounded by electrons. When a (positive) alpha particle approached sufficiently close to the nucleus, it was repelled strongly enough to rebound at high angles. The small size of the nucleus explained the small number of alpha particles that were repelled in this way.

What was rutherfords experiment?
he shot tiny alpha particles throug a piece of gold foil. -Apex
In Rutherfords gold foil experiment shown in Figure 4-1 alpha particles that bounce straight back from the foil have struck in the gold atoms?
No, they struck the nucleus of the atom. Since the alpha particles are positively charged and nucleus is positively charged as well, they repelled each other and alpha particles are repelled back
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.
Which type of particles did Rutherford fire at gold foil?
Rutherford fired alpha particles at the gold foil during his famous gold foil experiment. These alpha particles were positively charged and were emitted from radioactive elements.
Why was a vacuum used for Rutherford's gold foil experiment?
A vacuum was used in Rutherford's gold foil experiment to reduce interference from air molecules that could scatter the alpha particles, leading to inaccurate results. The vacuum helped create a controlled environment for the experiment, allowing the alpha particles to pass through the gold foil without deflection by air particles.
What was ernest rutherfords's experiment?

In Rutherfords gold foil experiment particles in dense atomic nuclei caused some alpha particles to bounce straight back from the gold foil.?
positive
What materials are needed for rutherfords gold foil experiment?
For Rutherford's gold foil experiment, you will need the following materials: thin gold foil, alpha particles, a source for the alpha particles, a fluorescent screen or detector to observe the scattered particles, and a vacuum chamber to prevent air molecules from interfering with the experiment.

What caused the deflection of the alpha particles in Rutherfords gold foil experiment?
A zinc sulfide coated screen surrounding the gold foil produced a flash of light whenever it was struck by an alpha particle. By noting where the flash occurred, the scientists could determine if the atoms in the gold foil deflected the alpha particles.
What was the purpose of the fluorescent screen in rutherfords experiment?
The purpose of the fluorescent screen in Rutherford's experiment was to detect the alpha particles that were deflected when they struck the gold foil. The screen would light up when hit by the alpha particles, allowing Rutherford to observe and measure the deflection pattern and infer the structure of the atom.
In Rutherfords gold foil experiment shown in Figure 4-1 alpha particles that bounce straight back from the foil have struck in the gold atoms?

Which type of particles did Rutherford fire at gold foil?
Rutherford fired alpha particles at the gold foil during his famous gold foil experiment. These alpha particles were positively charged and were emitted from radioactive elements.
How did Rutherford's alpha scattering experiment show that Thomson's plum pudding model of the atom incorrect?
Rutherfords experiment proved the existence of a nucleus as some alpha particles "bounced back" from the gold foil sample . Thomson model did not involve a nucleus and predicted just a slight deflection or none at all.
Where did most of the alpha particles fired at the foil go in the gold foil experiment?
Most of them went right through.
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.
