Why gold foil is used in Rutherford experiment?
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.

A diagram of the Geiger-Marsden (aka gold foil) experiment? Why yes, there is. A link is provided to a simple diagram. It should be mentioned that the "scintillatio…n screen" where the interactions occurred that produced the little blink of light was a film on the curved strip that surrounded the experiment. All the little dots of light had to be observed by an experimentalist. No detectors, no electronics, no computers, no nothin'. Just simple, smart experimental activity that had everything to do with the labor of intense observation over an extended period. Gotta love they guys who did it. And we name the experiment after them. Notice that it is the Geiger-Marsden experiment. These two cats were Rutherford's assistants, and they did all the work. We gotta give 'em their props.
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
The Rutherford gold foil experiment is also known as the Geiger-Marsden experiments. In them, alpha particle scattering was measured, and showed how a large focus was foun…d in such a way as to describe atoms having a dense nucleus. This experiment is not used for much today in any field other than focused particle physics, wherein it is the basis of most other calculations involving how atoms work.
The experiment provided evidence for a positively charged bundle in the center of the atom. We now know this to be the nucleus.
Yes , Rutherford's gold foil experiment was about the atomic structure. He bombarded 8000 alpha particles on the gold foil and the source of alpha particle was POLONIUM (an el…ement in periodic table). After bombarding rays, he observed that most of the rays passed without deflecting, and few rays deflected backward. By this , he concluded that most part of the atom is empty. That empty part is also called extra nuclear part or energy levels, shells or orbit . Nucleus lies in the centre of the atom which carries positive charge. It was his assumption which was right. Because two like charges always repel each other. since alpha particles carries positive charge and it can repeled by only positive charge. Electrons revolve in extra nuclear part.One thing that was wrong about Rutherford experiment was his assumption that eletron while revolving in the extra nuclear part continuously radiate energy.
yes there were problems withn rutherford's model but i dont know the problem
Rutherford discovered that atoms are mostly empty space except for the nucleus at the center of the atom.
Alpha radiation :) The point is that Alpha radiation doesn't pass through gold foil. Therefore there was an obvious issue when they were detecting particles passing through th…e foil every so often. This lead to the theory that objects consist of billions of atoms as opposed to being one solid object. Hope this helps! Sources - L. Robinson's Higher Physics
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.
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 stretc…h 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.
Rutherford's results indicated that most of the alpha particles went right through the gold atoms without being affected. He had expected this, because he knew… there must be relatively large space within atoms. However, he was astonished to see that a few alpha particles rebounded from the foil much as a ball rebounds from a solid wall. Rutherford had discovered the nucleus-the tiny, dense, positively charged centre of the atom. This was a tremendously important discovery.
What technology had to be invented before Ernest Rutherford could perform his experiments with gold foil?
A device able to detect alpha particles and count them.
due to its large atomic number
cuse the uv lithg had an effect on the eggs
Before Ernest Rutherford's landmark experiment with a few pieces of metal foil and alpha particles, the structure of the atom was thought to correspond with the plum pudding m…odel. In summary, the plum pudding model was hypothesized by J.J. Thomson (the discoverer of the electron) who described an atom as being a large positively charged body that contained small, free-floating, negatively charged particles called electrons. The plum pudding model also states that the negative charge of the electrons is equivalent to the positive charge of the rest of the atom. The two charges cancel each other causing and cause the electrical charge of the atom to be zero (or neutral). The faulty aspect of this model is that it was construed before the nucleus of an atom (and its composition) was discovered; which is where Rutherford's research comes in.
Rutherford made the following conclusions: Since most of the alpha particles passed straight through the gold foil without any deflection, most of the space within t…he atoms is empty. Since some of the alpha particles (which are big in size) were deflected by large angles or bounced backwards, they must have approached some positively charged region responsible for the deflection. This positively charged region is now called the nucleus. As very few alpha particles undergone the deflection, it was concluded that the volume occupied by the central region ( nucleus ) is very small. Since alpha particles which are relatively denser, were deflected by the central volume of charge, it shows that almost the complete mass of the atom must be within the central volume.
