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. If the foil were too thick, there would be no transmission of particles at all; the whole point was to demonstrate that most alpha particles passed through unchanged, but some of them scattered, which is only possible with a VERY thin foil.

1. It is used because gold was known to be a very inert element. 2. The use of gold had nothing to do with its reactivity, any more than the experiment had any connection to… chemistry. Rutherford wanted to fire alpha particles through the foil. Alpha particles are not very penetrating; a sheet of notepaper will stop most of them. To achieve a reasonable percentage of penetration the foil needed to be really thin. Gold is highly malleable; gold leaf can be made in thicknesses around 100 nm or 4 micro-inch. It was the best material for the job.
He established that atoms are made of protons, neutrons and electrons. Well sir, i was just wondering the same thing. I have to do a worksheet and answer it, no…t so lucky for me, this was one of my big questions. If anybody would like to answer this really soon, that would be oh so very helpful.Thank you, and have a nice day. ^That is no answer, just a sorry excuse The gold foil experiment proved that the atom is mostly empty space with a small, dense nucleus. True answer by Justin Wilkes
It demonstrated that there is positively charged nucleus and the atom is mostly empty spaced.
How would the results of rutherford's experiment with an aluminum foil be similar to his gold foil experiment?
they are both green on the periodic table of elements.... the alpha particles would follow the sam pattern. when the aluminum has a greater charge the particles would ha…ve a strong bend.
yes there were problems withn rutherford's model but i dont know the problem
He hypothesized that a beam of alpha particles would pass through thin sections of matter largely undeflected. He believed that some alpha particles would be slightly scattere…d whenever they encountered electrons.
In 1911, Ernest Rutherford conducted an experiment that proved that the mass of an atom is concentrated in the center (nucleus) of an atom. It also proved that an atom is most…ly empty space. In his experiment, he emitted positively-charged particles at a piece of gold foil. Many of the particles went straight through, some were deflected, and some were reflected.
due to its large atomic number
Suppose Rutherford had bombarded aluminum foil with alpha particles instead of the gold foil he used in his experiment What observations do you predict Rutherford would have made?
What Rutherford would have done was figure out the particles in the aluminum foil then take the alpha particles and mix them together. I think he would observe the protons, ne…utrons and electrons and observe the difference between the aluminum foil and gold foils movement of the particles.
If Rutherford made bombarded aluminum foil with alpha particles instead of gold foil what observations would he have used?
The angles formed in this experiment will have different angles than using gold foil as the atomic number is less in aluminium than the gold.As aluminium foil is more thick th…an of gold most of the rays wont completely pass through the foil.
protons are located in the nucleus of an atom
It would have been just different
What did Ernest Rutherford conclude about the nucleus of an atom based on his experiments using gold foil?
it was positively charged
The scattering pattern would differ, otherwise the results would be the same
What differences would you expect if beryllium foil were used instead of gold foil in the alpha-particle scattering experiment?
same result with less deflection
He discovered that some alpha particles were deflected by atoms. From this he concluded that the popular "plum pudding" model of an atom, where people thought that an atom was… a positive particle filled with smaller negative particles, was wrong. Instead he created the atomic model which has a nucleus (neutrons and protons) surrounded by much smaller electrons.
