Alpha particle scattering experiment was carried out by Rutherford in 1911 which is also known as Gold foil experiment
What differences would Rutherford have observed if he used aluminum?
He made several observations from the experiments. … What differences would Rutherford have observed if he used aluminum foil instead of gold foil?
More of the a particles would have passed through the aluminum foil unobstructed, and less would have been deflected at a large angle.
Why did Rutherford use gold instead of Aluminium foil?
Rutherford used gold for
his scattering experiment because gold is the most malleable metal and he wanted the thinnest layer as possible
. The gold sheet used was around 1000 atoms thick. Therefore, Rutherford selected a Gold foil in his alpha scatttering experiment.
What would have happened in Rutherford’s experiment if he had used a thin sheet of copper instead of a thin sheet of gold?
Rutherford might have observed that
the alpha particles did not deflected as much
. This is because the nuclei of copper atoms have fewer protons and thus are smaller and therefore have less of a total charge.
Can a thin foil of Aluminium be used in place of gold Au in Rutherford experiment give suitable explanation?
can a thin foil of aluminium be used in place of gold in rutherford experiment? give suitable explanation. 1)
Aluminum is less ductile
, hence such thin foil will not be formed as the experiment requires. … And due to these factors failure of the experiments will be caused.
Why was Rutherford’s model rejected?
Rutherford’s model was unable
to explain the stability of an atom
. According to Rutherford’s postulate, electrons revolve at a very high speed around a nucleus of an atom in a fixed orbit. … Rutherford’s theory was incomplete because it did not mention anything about the arrangement of electrons in the orbit.
Why did Rutherford use gold?
He chose gold
because it can be pounded into sheets that are only 0.00004 cm thick
. Surrounding the sheet of gold foil, he placed a screen that glowed when alpha particles struck it. It would be used to detect the alpha particles after they passed through the foil.
Why did Rutherford use rays and not rays?
Known Theory of Uranium Radiation
From Becquerel’s work, it was known that the radiation would penetrate solid material, but it was not known through how much material. … From this theory,
Rutherford hypothesized that the rays emitting from uranium would be complex, composed of different types of rays
.
What did Rutherford’s alpha scattering experiment prove?
Rutherford and coworkers were able to demonstrate that the
alpha particle was an atom of helium (later to be determined to be a nucleus of helium)
, and that helium gas would accumulate or be entrapped in minerals that contained radium.
What was the order of thickness of gold foil?
Because it is unusually ductile, gold can be made into a foil that is only
0.00004 cm thick
. When this foil was bombarded with -particles, Geiger found that the scattering was small, on the order of one degree. These results were consistent with Rutherford’s expectations.
What was the conclusion of Rutherford experiment?
| Observations Conclusion | Few particles bounce off the nucleus Indicates that all the positive charge and mass of the gold atom were concentrated in a very small volume within the atom. |
|---|
Why did the alpha particles go through the gold foil?
| What happened Rutherford’s conclusions | Most of the alpha particles did pass straight through the foil. The atom being mostly empty space. |

How did the gold foil experiment work?
Physicist Ernest Rutherford established the nuclear theory of the atom with his gold-foil experiment. When
he shot a beam of alpha particles at a sheet of gold foil, a few of the particles were deflected
. He concluded that a tiny, dense nucleus was causing the deflections.
Why did Rutherford use ZnS?
Hi, ZnS (Zinc Sulfide) screen was used
because it emits a flash of light when struck by an alpha particle
. This is a phenomenon called Radio luminescence in which a flash of light is observed on the screen when acted upon by a radioactive substance.
What are the two main features of Rutherford’s atomic model?
The salient features of this model are as follows: (i) The atom contains a central part called nucleus which is surrounded by electrons. (ii) The nucleus of an atom is positively charged. (iii)
The size of the nucleus is very small as compared to the atomic size.
What was the major drawback of Rutherford atomic model?
One major drawback of Rutherford’s model was
the comparison of electrons with the planets in the solar system
. Thus, when an electron moved around the nucleus continually, it should radiate energy, i.e. lose energy. As a result it should be gradually pulled towards the nucleus and end up colliding with it.
