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.
Who discovered the nucleus using his gold foil experiment?
Rutherford by bombarding gold foil with positively charged particles and noting that some particles were widely deflected.
Rutherford theorized that atoms have a dense positive center or nucleus How the evidence for this conclusion illustrated in the animated gold-foil experiment?
it is awsome
In Rutherfords gold foil experiment shown in Figure 4-1 alpha particles that bounce straight back from the foil have struck in the gold atoms?
No, they struck the nucleus of the atom. Since the alpha particles are positively charged and nucleus is positively charged as well, they repelled each other and alpha particles are repelled back
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).

Based on his experiment Rutheford concluded that atoms were?
The conclusion was that an atom contain a positive nucleus.
What is the principal reason for using neutrons to bombard nucleus?
They are not repelled by the nucleus.
What experiment convinced Ernest Rutherford thet atom has a small positively charged nucleus?
Rutherford used the gold foil experiment to figure out that an atom had charged particles in the nucleus
Who provided evidence for the exsitist of an atomic nucleus?
This is the well known gold foil experiment: alpha particles are scattered by the atomic nucleus.
What conclusion about the atom came from Ernest Rutherfords famous gold foil experiment?
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
What part of the atoms caused the particles to bounce?
The heavy, dense nucleus of the atom caused the alpha particles to bounce back in Rutherford's experiment.
What did Ernest Rutherfords gold foil experiment demonstrate about an atom?
The conclusion was that an atom has a nucleus (center) with a positive charge.
What did ernest rutherfords gold foil experiment demonstrate about atoms?
The conclusion was that an atom has a nucleus (center) with a positive charge.
What was the conclusion of Rutherford's gold foil experiment in terms of an atom's mass and volume?
Rutherford found that when when he aimed alpha particles at a thin sheet of gold foil, that some of the particles were deflecteted and didn't go straight through the foil. The reason for this turned out the be that they ran into the nucleus. Most of the particles did go straight through, so Rutherford concluded that the atom was mostly empty space. He also concluded that the center of the atom contained the nucleus and had positively charged particles he called protons.
