What was the significance of the particles that reflected back from the gold foil?
Hope you mean the famous alpha particle scattering experiment performed. Alpha particle being positively charged get reflected. This confirms that there have to be positively charged particles within the gold foil. Moreover this scattering is very less compared to those just passing through gold foil. Rutherford as he made an observation of these he came to the conclusion that the positively charged core is so tiny and its radius of the order of 10-14 m. The radius of the atom was already found to be 10-11 m. So it becomes clear that the nucleus is 1000 times smaller than the atomic size
What else can I help you with?
Rutherford theorized that atoms have a dense positive center or nucleus How the evidence for this conclusion illustrated in the animated gold-foil experiment?
In Rutherford's gold-foil experiment, a narrow beam of alpha particles was aimed at a thin sheet of gold foil. Most alpha particles passed through the foil without deflection, but some were deflected at large angles or even reflected back, indicating a concentrated positive charge at the center of the atom. This observation led Rutherford to conclude that atoms have a dense positive center or nucleus.
What happened to the alpha particles as they hit the gold foil?
They stop.
The kind of particle Rutherford used to shoot through gold foil?
Rutherford shot high-energy alpha particles (two protons and two neutrons, or a helium nucleus) at the gold foil. A small fraction of these alpha particles bounced back, and that is how Rutherford discovered the nucleus.
Which type of particles did Rutherford fire at gold foil?
Rutherford fired alpha particles at the gold foil during his famous gold foil experiment. These alpha particles were positively charged and were emitted from radioactive elements.
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
How did gold foil experiment show that there is a nucleus in the atom?
The gold foil experiment showed that there is a nucleus by how the alpha particles(positively charged particles) were deflected and changed course by the foil. It showed that the atom is made of mostly empty space because most particles went through the foil. Some of the particles though were deflected to the sides of the container around the foil and some where even reflected back at the light almost. Rethurford (or however you spell is name lol search it) theorized that there is a small nucleus that is positively charged that some particles came close to and were deflected away because the nucleus had an effect on them. Some particles hit the nucleus exactly and were reflected back only because it was positively charged if it had been negativly charged it wouldn't have went back to the light.
The gold foil experiment led to the conclusion that each atom in the foil was composed mostly of empty space because most alpha particles directed at the foil?
Most alpha particles passed straight through the foil, suggesting that atoms are mostly empty space. Some alpha particles were deflected at small angles, indicating the presence of a small, dense nucleus. A few were even reflected back, showing that the nucleus is positively charged.
In Rutherfords gold foil experiment particles in dense atomic nuclei caused some alpha particles to bounce straight back from the gold foil.?
positive
When Rutherford performed his metal foil experiment did the alpha particles pass straight through the foil or bounce back?
In Rutherford's metal foil experiment, some alpha particles passed straight through the foil, while others were deflected at various angles. A small fraction of the alpha particles even bounced back towards the source. This led Rutherford to conclude that atoms have a small, dense nucleus at their center.

What bounced back in Rutherford's gold foil experiment?

How did the result of gold foil experiment lead Rutherford to recognize the existence of atomic nuclei?
By beaming alpha particles through gold foil and witnessing some of them deflecting, there had to be a mass larger than an alpha particle in the atomic structure. This disproved the plum pudding theory of the atom, as electrons would not have had enough mass to deflect the larger alpha particles.
