Can we use Aluminium foil in Rutherford experiment?

A foil of small atoms like aluminum, having a very less number of positive charges (Z=13) will not be able to repulse a fast moving alpha particle to return.

What would happen if Rutherford used aluminum foil?

Alpha particle scattering experiment was carried out by Rutherford in 1911 which is also known as Gold foil experiment. If thick foil is used then it will result in the change of scattering angles thereby affecting the predictions of the experiment.

Can Aluminium be used in alpha particle scattering experiment?

Assertion: Aluminium foil cannot be used in the α – particle scattering experiment. Reason: Aluminium is a highly malleable metal.

Can a thin foil of Aluminium be used in place of gold Au 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 did Rutherford want a thin foil?

Rutherford used gold for his scattering experiment because gold is the most malleable metal and he wanted the thinnest layer as possible. The goldsheet used was around 1000 atoms thick. Therefore, Rutherford selected a Gold foil in his alpha scatttering experiment.

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 thin gold foil?

Gold was used because it was the only metal that could be rolled out to be very, very thin without cracking. Since the gold foil was very thin, it was thought that the alpha particles could pass straight through it, or possibly puncture the foil. most of the alpha particles did pass straight through the foil.

Which metal is used by Rutherford in his experiment?

gold foil
Rutherford used a very thin gold foil in the alpha ray scattering experiment. He used a gold foil over all the other metals as gold is the most malleable metal available and it can easily be beaten into very thin sheets. The gold sheet used in this experiment was around 1000 atoms thick.

When a silver foil Z 47 was used in an?

α-ray scattering experiment
When a silver foil (Z = 47) was used in a α-ray scattering experiment, the number of α particles scattered at 30∘ was found to be 200 per minute. If the silver foil is replaced by aluminium (z = 13) foil of same thickness, the number of α -particles scattered per minute at 30∘ is nearly equal to.

When a silver foil Z 47 was used in an Alpha?

When a silver foil (Z=47) was used in an α-ray scattering experiment, the number of α partied scattered at 30∘ aws found to be 200 per minute. If the silver foil is replaced by aluminium (z=13) foil of same thickness, the number of α-particles scattered per minute at 30∘ is nearly equal to.

What would happen if aluminum was used in the gold foil experiment?

The scattering angles would have changed, but the qualitative results would also change: the reason Rutherford chose gold was because it is EXTREMELY malleable. One can stretch gold foil until it is only a few atoms thick in places, which is not possible with aluminum.

Why did Rutherford use heavy metals?

We have studied that in the Rutherford ‘s experiment by using heavy metals like gold and platinum, a large number of α – particles sufferred deflection while a very few had to retrace their path . As a result,the number of α- particles will be quite less and the particles which are deflected back will be negligible.

What is the principle of Rutherford’s experiment?

Principle of Rutherford’s experiment By bombarding a very thin gold foil with alpha particles, Hans Geiger and Ernest Marsden, both students of Rutherford, observed that a small fraction (1 in 8000) of these particles were deflected at large angle as if it bounced off a heavy obstacle.

What is Rutherford scattering?

Rutherford’s Gold foil scattering experiment Introduction: In physics, Rutherford scattering is a phenomenon that was explained by Ernest Rutherford in 1909, and led to the development of the Rutherford model (planetary model) of the atom, and eventually to the Bohr model.

How did Rutherford count the scintillations of alpha particles?

It was in darkness and with the naked eye, that Rutherford, Geiger and Marsden counted the scintillations due to the impacts of alpha particles on a screen of zinc sulphide. Alpha backscattering on nucleus Rutherford observed the backward bounce of some alpha particles as projectiles sent on the atoms of a thin gold foil.

What materials did Rutherford use to make his spectroscopes?

He actually used also Aluminium, Silver, and Copper. He did so because he wanted to prove that the Rutherford cross section was proportional to . In any case, he needed to use malleable material (metals) in order to achieve a micrometer-thin foil to prevent the entire beam to be absorbed by the target.
