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.

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.
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
The experiment provided evidence for a positively charged bundle in the center of the atom. We now know this to be the nucleus.
It demonstrated that there is positively charged nucleus and the atom is mostly empty spaced.
yes there were problems withn rutherford's model but i dont know the problem
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
Rutherford was a scientist who shot alpha particles through a very thin sheet of gold foil. The results of this experiment are the following: -Almost all alpha particles passe…d right through the Gold foil -A few alpha particlas were deflected and repelled .....These conclusions show that the majority of the atom of gold is empty space except for a small, positively charged nucleus. This nucleus is the reason why some alpha particlas were deflected(Alpha particles have a positive charge, which is repelled by a positive nucleus).
protons are located in the nucleus of an atom
Because he bombarded the alpha rays on thin foil of gold and alpha rays can not pass through air or gases.
E. Rutherford developed his atomic model due to the results of his gold foil experiment. His atomic model describes a small central, dense core and a surrounding volume of cha…rged particles.
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.
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.
