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 model. 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.

Thanks for the feedback!
It is because gold is soft and most malleable metal and can be made into very thin sheets. Rutherford experiment consisted of bombardment of Alpha particles at the sheet of …any substance.So, he wanted a sheet as thin as possible and gold foil was the most suitable choice for it. :):):) hope this helps
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 conclusions were that the nucleus in an atom must:- (1) Be positive as it repelled the positive alpha-particles (2) Have a high mass, as the deflections were massive … (3) Be very small as only a few of the particles were deflected
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 Earne…st Rutherford's direction. You need a link to the Wikipedia post on this ground-breaking experiment, and we've got one for you.
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.
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
While he was a professor at the University of Manchester, England.
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
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.
What did Ernest Rutherford conclude about the nucleus of an atom based on his experiments using gold foil?
it was positively charged
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.
The Gold Foil experiment demonstrated the (at the time) surprisingresult that atoms had nuclei. The prevaling model for atoms at thetime has been described as "grapes in Jell-…O" (with electrons -"grapes" - suspended in a uniform field of positive charge, the"Jell-O"), and the alpha particles Rutherford (actually, it was hisstudents, Hans Geiger and Ernest Marsden) was shooting at the foilwere expected to pass nearly straight through with only minordeviations. Instead, what was observed was what Rutherford described as "firinga 15-inch shell at a piece of tissue paper and having it come backand hit you," because it turns out that all the positive charge inthe atom is concentrated within a very small region ... thenucleus, and the alpha particles recoiled quite strongly from thisconcentration of charge.
