∙ 11y agoOk, Rutherford noticed that if the alpha particles can pass through thin glass, then it may be possible for it to pass through a very then foil. Although gold has tougher properties than glass, its atoms consist of electrons where the electrons are free to move around. Because these electrons are relatively small compared to the alpha particle, the alpha particle had enough energy and velocity to pass through the gold foil. Once this happened some of the alpha particles were deflected (just a very few of them). this led Rutherford to conclude that there was a particle with a positive charge (protons) in the atoms of gold and that atoms are made of mostly empty space. (Warning: i am not a professional, but a senior high school student who loves chemistry and physics)
[The observation that some of the particles rebounded was made by Rutherford's experimenter students, Ernest Marsden and Hans Geiger. Both of whom went on to further studies in Physics.]

∙ 14y agoIn the Geiger-Marsden experiment (the gold foil experiment or the Rutherford experiment), the alpha particles pass through the electron cloud of the atom. The alpha particle, which is composed of a pair or protons and a pair of neutrons fused together, is a helium-4 nucleus. It's several thousand times more massive than a little electron, so it slices through the electron cloud with no effort at all. A link can be found below to check facts, see a diagram and learn more.

∙ 6y agoRutherford thought that the only way what he observed when the bulk of the positively charged particles passed through the gold sample could be true is if most of the mass of an atom was concentrated at a single point in that atom. This was the dividing line between the raisin pudding model of the atom and the model that had most of the mass of the atom concentrated in a nucleus.

Who is Rutherford and the gold foil experiment?
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 passed 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).
In Rutherfords gold foil exepirement Rutherford concluded that the atom is mostly empty space with a small massive positivley charged center because?
In Rutherford's gold foil experiment Rutherford concluded that the atom is mostly empty space with a small massive positively charged center because most of the electrons passed through but a few were wildly deflected.
What is the explanation for the scattering experiment of Rutherford?
Rutherford conducted an experiment in which Alpha particles were fired at a gold nucleus. Most of the particles passed through unaffected. However, some were deflected by a small amount whilst an even smaller number of the particles were deflected completely. This led to the conclusion that the atom has an extremely small, central, positively charged nucleus. As both the positive alpha particle and the positive nucleus repel each other by electrostatic forces. The fact that only a small amount of particles are deflected shows that the nucleus is only a tiny central part of the atom.
How was it proved that whole mass of an atom is located at its centre?
,Rutherford alpha scattering experiment proved that most of the particles passed through the gold foil undeflected it means most of the volume occupied by atom is empty and few particles deflected it means there is centre of positive charged called nucleus,so hence proved whole mass of an atom is located in the centre..
What is a steady flow?
the flow is said to be steady flow if every particle passing through a point follows the same path as the particles passed through the point earlier.
What is the purpose of Earnest Rutherfords gold-foil experiment?
to find out if all element has the same mass or can pass through the tin foil in other words not all passed through
How did the results of Rutherfords gold foil experiment differ from his expectations?
Everyone thought that the alpha particles would go through the gold- foil with little deflection. When the alpha particle passed straight through the gold atoms with no deflection or bounced straight back a small fraction bounced off at a large angle, or bounced straight back to the source. Rutherford came up with a new theory of the atom, that the atom is mostly empty space and in the center there is a nucleus. this is known as the nucleus atom.
In rutherfords gold foil experiment he concluded that the atom is mostly empty space with a small massive positively chargeed centrer because?
When the beam of electrons passed through the gold foil, some were deflected at odd angles. This indicated the presence of a more massive portion of the atom that could be explained by the raisin pudding model.

How is the Rutherford Experiment Done?
To do the Rutherford Experiment, you have to shoot alpha particles at gold foil to and see where the particles pass through and where they do not. This will give you a general idea of what Rutherford did to discover the nucleus of an atom. However, alpha particles are very hard to come upon, as they are the nucleus of Carbon. Rutherford knew that alpha particles are about 7000 times more massive than electrons and are positively charged and the charge is twice the magnitude of the charge of electrons.when Rutherford directed a beam of alpha particles at a thin gold foil,he found that almost all particles passed through it without deflecting.A very small were deflected at an angle, however, and a few actually bounded back toward the particle source.
How was the Rutherford experiment done by Rutherford?
In 1910, Rutherford and his coworkers were studying the angles at which alpha particles were scattered as they passed through a thin gold foil. Most particles passed through undeflected, though a few were found to be scattered at large, some even in the direction they had come. This meant they had collided with an object much more massive than the particle itself, but so small that only a few aplha particles encountered them. Showing that the atom was composed of a small dense massive center surrounded by low mass electrons.
What did the particles in Rutherford' s experiment do?
Rutherford was expecting the result to be what JJ Thomson had predicted. That the Alpha Particles just pass through the gold foil, not rebound, like the result. JJ Thomson thought of this result because of his plum pudding model.
What was Rutherfords main contribution to science?
He discovered that most of the mass of an atom and all of thepositivecharge are in the centre. Most of the atom is 'empty' space, occupied by electrons, which orbit thenucleus.Gold Foil ExperimentHe shot streams of alpha particles (Helium nuclei) through a thin gold foil and discovered most of them passed through and a minority deflected back. As alpha particles are positively charge, that means the nucleus of atoms are also positive as it deflects alphas away. (pos-pos,repeland neg-pos, attract)
What is the explanation for the scattering experiment of Rutherford?
Rutherford conducted an experiment in which Alpha particles were fired at a gold nucleus. Most of the particles passed through unaffected. However, some were deflected by a small amount whilst an even smaller number of the particles were deflected completely. This led to the conclusion that the atom has an extremely small, central, positively charged nucleus. As both the positive alpha particle and the positive nucleus repel each other by electrostatic forces. The fact that only a small amount of particles are deflected shows that the nucleus is only a tiny central part of the atom.
In Rutherfords experiment why wouldn't the electrons in the atoms of the gold foil affect the paths of the alpha particles?
Electrons are so small that they have no affect. The alpha particles were 2 protons and 2 neutrons being shot thru, even though the electrons have a negative charge..they are so small and take up so little space, the alpha particles probably n ever even came near them.
What did Rutherford conclude when most particles fired at metal passed straight through?
That the atom was mostly empty space
