Rutherford's experiment with the gold foil was done by his assistants, Geiger and Marsden. (We gotta give 'em their props. The experiment, by the way, carries the names of those two guys. They did the work.) Let's check it out. An alpha source was set up. Alpha particles are helium nuclei, two protons and two neutrons. A shielded block with a hole in it served as the source. Radon was put inside. The hole acted as the only means of escape for the alpha particles. The hole was pointed at the foil. The foil was set up a short distance from the source, and in a line with the opening in the shield block. (They needed to "aim" the source at the foil.) Using the foil as the center of the collision or scattering events, they took a long strip of material that was coated with zinc sulfide and set it up in an almost complete circle. Now they had an "arena" for the event with the target at the center and the little strip of scintillant material around it. They turned off the lights. That way they could see the scintillations, the little blinks of light that resulted when an alpha particle hit the screen. Remember that they are looking at the screen and not the target. They expected all the particles to go right through the target, but they noticed some reactions along the sides. Not many or often, but they were there. Hit the links for the diagrams.

Who discovered the nuclear atom?
The nuclear atom was discovered by Ernest Rutherford. He did it with a gold foil experiment.
Who provided evidence for the existence of a nucleus in an atom?
Ernest Rutherford
How did Rutherford discover nucleus?
The atomic nucleus was discovered by Ernest Ruthorford in the 1800's with his gold foil experiment. The earliest records of the biological (or cell) nucleus are from Antonie van Leeuwenhoek in 1719.
The gold-foil experiment led scientists to conclude that an atom's?
The gold-foil experiment led scientists to conclude that an atom's volume is mainly unoccupied.
Why was ernest Rutherford so surprised about his experiment?
Rutherford expected the alpha particles to shoot right through the gold foil. At the time it was assumed that anatom was a mix of electrons and protons. When Rutherford shot the particles through the gold foil some of theparticles reflected back, while most just shot right through. This indicated there was a small dense positivelycharged nucleus in the atom.
What is the name of the scientists who first proposed that atoms have a nucleus?
Ernest Rutherford, following the "gold foil" experiment.
Who discovered the nuclear atom?
The nuclear atom was discovered by Ernest Rutherford. He did it with a gold foil experiment.
What experiment convinced Ernest Rutherford that the atom has a small positivity charged nucleus?
th gold foil experiment
Which statement is consistent with the results of Rutherford's gold foil experiment?
The statement that is consistent with the results of Rutherford's gold foil experiment is that atoms are mostly empty space with a dense, positively charged nucleus at the center. Rutherford's experiment showed that most of the alpha particles passed through the foil undeflected, indicating that the nucleus is small and concentrated.
How did Ernest Rutherford discover nucleus?
Gold foil experiment.
Who discoveredthe nucleus using his gold foil experiment?
Rutherford
How can we perform Rutherford's Gold Foil Experiment work in a classroom?
Rutherford\'s gold foil experiment can be performed in a classroom setting by using marbles, wooden blocks, and books as the materials.
What wa Rutherford's gold foil experiment?
The gold foil experiment supplanted the plum pudding theory. The gold foil experiment led to the discovery that most of the atoms mass is located in the dense nucleus.
Who conducted the gold foil experiment to discover the nucleaus?
Ernest Rutherford was responsible for the Gold Foil experiment. A great portion of Ernest Rutherford's research included the study of alpha particles.
Who is series of experiments identified the nucleus of an atom?
The gold-foil experiment
What year did Rutherford do his experiment?
The Geiger-Marsden experiment, which is also called the gold foil experiment or the Rutherford experiment, was conducted by Hans Geiger and Ernest Marsden in 1909, under Earnest Rutherford's direction. You need a link to the Wikipedia post on this ground-breaking experiment, and we've got one for you.
Who used the gold foil experiment?
Ernest Rutherford conducted the gold foil experiment in 1909 at the University of Manchester. He aimed to investigate the structure of the atom and discovered that atoms have a small, positively charged nucleus at their center.
