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.

Is the nucleus a very small region of the atom?
Yes. It was shown by Rutherford's alpha scattering experiment.
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.
Who said atoms were made up of subatomic particles?
Rutherford proved it it from his alpha-particle scattering experiment.
Why did Rutherford use alpha particles rather than electrons for his scattering experenment?
Because the alpha particles are positively charged. In order for the experiment to work, the positive alpha particles must be attracted to the negatively charged gold foil.
Why a spherical sulphide screen is used in alpha ray scattering experiment?
Because it was cheap and had good fluorescence properties, meaning high light output and therefore better energy resolution.
Rutherfords alpha scattering experiment showed that the charge on the nucleus of the atom must be?
positive

Why was ernest Rutherford important to society?
He completely changed the model of the atom using his simple alpha scattering experiment.
What will happen if the beta particles would be there in the scattering experiment instead of alpha particles?
then you would get a girlfriend instead of asking questions on wikianswers
Who discovered that atoms were composed of protons and neutrons?
neutrons were discovered by james chadwick by an experiment which was started by madam curie. protons were discovered by rutherford in his alpha ray scattering experiment
Rutherford's alpha-scattering experiment showed that the charge on the nucleus of the atom must be a.positive b.neutral c.negative d.too small to be detected?
positive
Why did Rutherford use alpha particles rather than electrons for his scattering experenment?
Because the alpha particles are positively charged. In order for the experiment to work, the positive alpha particles must be attracted to the negatively charged gold foil.
What experiments demonstrated that atoms are mostly empty space?
The alpha particle scattering experiment by Ernest Rutherford (1911) demonstrates that more than 99.9% of an atom contains empty space.
What did Rutherford scattering experiment reveal about atoms?
The principal conclusion was that any chemical element has a positive charged central nucleus.
What were the predictions for the alpha scattering experiment?
some of this particles were scatter some pass through without any deflection some were reflected back in the same direction
