Is the nucleus a very small region of the atom?
Yes. It was shown by Rutherford's alpha scattering experiment.
Who said atoms were made up of subatomic particles?
Rutherford proved it it from his alpha-particle 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.
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 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.
What was the alpha source in Rutherford scattering lab?
As alpha source E. Rutherford used radium.
The scattering of alpha particles by thin metal foils established that?
Nuclear physics
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 has the author Steven Joe Crutchfield written?
Steven Joe Crutchfield has written: 'An optical model analysis of 41 MeV alpha particle scattering' -- subject(s): Particles (Nuclear physics), Scattering (Physics)
Rutherfords alpha scattering experiments showed that the charge on the nucleus of the atom must be?
The atomic nucleus is positive because contain protons.
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
What caused the deflection of the alpha particles in Rutherford's gold foil experiment?
The alpha particles scatter from the atomic nuclei in the gold foil. The repulsive electrostatic force between the nucleus and the alpha particle (because both are positively charged and like charges repel) deflects the alpha particle. Because of the large mass and (relatively) large energy of the alpha particles in Rutherford scattering experiments, the alpha particles are largely unaffected by the electrons in the gold atoms. More accurately, the scattering of the alpha particles from the electrons produces small angular deflections.Because the nucleus is small -- approximately 1/10000th the size of the whole atom -- most of the time the alpha particles will pass through the atom with little or no deflection. But occasionally, the alpha particles will start on a trajectory that, without the electrostatic deflection, would take them very close to the nucleus. In such cases, the electrostatic force produces a large angular deflection and can even scatter the alpha particles backwards. If the positive charge in the atom were distributed over the entire size of the atom, the likelihood of having such a large-angle scattering would be much smaller than it was (is) observed to be. Thus, the original experiments demonstrated that the positive charge in atoms is confined to a small region at the very center of an atom. Indeed, the data also provided an estimate of the size of the nucleus. More advanced analyses of such scattering experiments with modern equipment but using electron beams have provided detailed measurements of nuclear diameters for a wide range of atomic nuclei.
