The alpha particle scattering experiment was conducted by Ernest Rutherford and his team in 1909 at the University of Manchester. This experiment led to the discovery of the atomic nucleus and revolutionized our understanding of the structure of the atom.

Why is gold foil used in the alpha particle scattering?
Hi I believe the answer to be because of its high density. Gold or Aurum (Au) is very dense and hence will 'reflect'and 'deflect' alpha particles, which are helium nuclei. Beta particles are electrons Hope that helps
Rutherford's experiment with alpha particle scattering by gold foil established what?
E. Rutherford, H. Geiger and E. Marsden discovered that all atoms have a positive charged nucleus. The electrons orbits this nucleus. Rutherford's experiment established what an atom looks like. When Rutherford sent alpha particles toward the gold foil, some passed while others bounced back. He collected the data and made a model of the atom. The only reason why some rays went through while others bounced back because of the composition of the atom in the gold foil.
What is the electrical charge of an alpha particle?
The electric charge of an alpha particle is positive. An alpha particle is a helium nucleus (which being a nucleus has a positive charge)
What is the charge of an alpha particle?
An alpha particle has a charge of 2, which means it is positively charged.
How does large angle alpha particle scattering give evidence for a nuclear model of atom?
The significant deflection of alpha particles in the Rutherford gold foil experiment suggests that most of the atom's mass is concentrated in a small, dense nucleus. The scattering pattern supports the idea that the nucleus is positively charged and surrounded by mostly empty space, with electrons moving around it. This provided key evidence for the nuclear model of the atom, eventually leading to the development of the modern understanding of atomic structure.
Who said atoms were made up of subatomic particles?
Rutherford proved it it from his alpha-particle scattering experiment.
What did the alpha scattering experiment reveal?
The alpha radiation in the experiment was detected by using a microscope and a fluorescent screen. When an alpha particle strikes the screen, the coating will fluoresce, and it will give off a "flash" of light. This small flash of light can be picked up by the investigator using the microscope.
Rutherfords alpha scattering experiment showed that the charge on the nucleus of the atom must be?
Rutherford's alpha scattering experiment showed that the charge on the nucleus of the atom must be positive because the alpha particles were deflected by the concentrated positive charge in the nucleus.
Why can Rutherford's experiment not explain scattering of acute angles?
The experiment explains all angles as a measure of how close the alpha particles travelled to the nuclei. An acute angle means that the particle virtually hit the nucleus and was directly rebounded.
What are the alpha scattering equipment?
Alpha scattering equipment refers to devices used to study the deflection and scattering of alpha particles when they collide with a target material. This equipment typically includes a particle accelerator to generate alpha particles, a target material to interact with the particles, and detectors to measure the deflection angles and energies of the scattered particles. Examples of alpha scattering equipment include alpha spectrometers and Rutherford scattering apparatus.
How could an alpha particle strike the phosphor screen on the same side of the foil as the alpha particle source?
An alpha particle could strike the phosphor screen on the same side of the foil as the alpha particle source if it undergoes a scattering event with a nucleus that causes it to change direction and travel back towards the same side. This scattering event can happen due to the strong Coulomb interaction between the positive charge of the alpha particle and the positive charge of the nucleus.
What Led to the discovery of the nucleus?
Alpha particle ie doubly ionized helium atom scattering by the gold foil experiment formed the basis for the discovery of nucleus. The experiment was done by Marsden and Geiger but the experimental observation was commented and final conclusion derived by Rutherford.
What is the scattering experiment?
The scattering experiment of E. Rutherford and his team lead to the disvovery of the proton and to a new atomic model. Alpha particles colliding an atom are scattered by the positive atomic nucleus containing protons.
What did Rutherford discover atoms?
Rutherford by passing interpretation about the famous alpha particle scattering experiment came to the conclusion that the positively charged nucleus is of small size of the order of 10-15 m where as the atom size is of the order of 10-11m

What happens when the positively charged alpha particle hits the positively charged nucleus?
Alpha particles interact with atomic nuclei by what is called scattering. An atomic nucleus will recoil from the scattering event somewhat, but the heavier the nucleus being "hit" by the alpha particle, the more the alpha particle will "bounce off" that nucleus. These interactions are not as "physical" as some we are familiar with, like billiard balls acting on each other, but the analogy is a good one. We actually say the alpha particle is scattered and comes away with less energy and the nucleus comes away having taken a bit from the alpha particle. With very small nuclei, the results are much more dramatic, particularly when we look at those elements with the lowest atomic numbers. As you can imagine, the smaller the atom, the more it reacts in the scattering process. A hydrogen-1 nucleus will "go flying" if it is involved in a scattering event with an alpha particle. And you can easily visualize that, too. Use the links below to related questions to learn more.
What is a radioactive particle that is made up of two neutrons and two protons?
Used by Rutherford in his experiment made of two protons and two neutrons are alpha particles. Rutherford discovered the nucleus using his gold foil experiment.
