What is the explanation for the scattering experiment of Rutherford?
Wiki User
∙ 14y ago
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.

Why was ernest Rutherford important to society?
He completely changed the model of the atom using his simple alpha scattering experiment.
Which statement is consistent with the results of Rutherford's gold foil experiment?
In Rutherford's gold foil experiment atoms are mostly empty space.
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 were the surprising results of Rutherford's gold-foil experiment?
The most surprising fact about Rutherford's experiment is that some of the atoms bounced backwards while others scattered.
What is the dense positively-charged mass in the center of an atom?
This can refer to either the nucleus or to an individual proton that makes up the nucleus. Because only protons and neutrons occupy the nucleus, it has a positive charge.
Is the nucleus a very small region of the atom?
Yes. It was shown by Rutherford's alpha scattering experiment.
Which scientist said electrons orbit the nucleus in distinct orbit?
Rutherford, using his gold foil 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.
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.
Why was ernest Rutherford important to society?
He completely changed the model of the atom using his simple alpha scattering experiment.
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
Which of the following provided evidence that most of the mass of the atom as well as all of the positive charge is concentrated in a very small core the nucleus?
The scattering of alpha particles by a metal foil.
Who discovered the size of the nucleus scattering?
Rutherford
What did Rutherford scattering experiment reveal about atoms?
The principal conclusion was that any chemical element has a positive charged central 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.
