The positively charged nucleus of the atom, which contains protons and neutrons, is what causes particles to bounce back due to electrostatic repulsion. When an incoming particle has the same charge as the nucleus, such as another positively charged particle, they will repel each other, causing the incoming particle to bounce back.

In Rutherford's gold foil experiment particles in dense atomic nuclei caused some alpha particles to bounce straight back from the gold foil.?
positive
In Rutherford's gold experiment particles in dense atomic nuclei caused some alpha particles to bounce straight back from the gold foil?
Yes, in Rutherford's gold foil experiment, he observed that some alpha particles were deflected at very large angles and even bounced straight back, indicating that they were hitting something small and dense (the atomic nucleus) within the gold foil. This observation led to the development of the nuclear model of the atom.
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.
How did Rutherford know the nucleus was positively charged?
Rutherford conducted the famous gold foil experiment, where he observed that some alpha particles were deflected back at large angles when they passed through thin gold foil. This led him to propose that the positive charge of an atom is concentrated in a small, dense region called the nucleus.
Why did Rutherford propose a new model of the atom?
Rutherford proposed a new model of the atom because his experiments showed that the existing plum pudding model could not explain the results of his gold foil experiment. He found that some particles were deflected at large angles, suggesting a concentrated positive charge at the center of the atom. This led to the development of the nuclear model of the atom.
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.
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?
Alpha particles that bounce straight back in Rutherford's gold foil experiment have struck the nucleus of gold atoms. This led to the discovery that atoms have a concentrated, positively charged nucleus at their center, with most of the atom being empty space.
What did Rutherford say about the small number of particles that bounced straight back?
Rutherford fired alpha particles at a sheet of atoms in order to determine the atomic structure. The alpha particle is positively charged. Those particles that bounce straight back are the ones that hit the nucleus of the atom and were repelled by the nucleus's positive charge.
What causes some of the alpha particles to bounce straight back from the gold foil?
Some of the alpha particles bounce straight back from the gold foil because they come very close to the densely packed positive nucleus of an atom, leading to strong repulsion due to positive charges. This results in a significant change in direction or even a complete reversal of their path.
What size particles does the wind usually skip and bounce for short distances?
Wind can skip and bounce particles that are small and light, such as sand and dust particles. These particles are able to be carried by the wind and lifted off the ground, allowing them to move horizontally for short distances before settling back down.
In Rutherfords gold foil experiment particles in dense atomic nuclei caused some alpha particles to bounce straight back from the gold foil.?
positive
What causes particles in matter to move back and forth?
Particles in matter move back and forth due to thermal energy, which causes them to vibrate. This vibration is a result of the kinetic energy of the particles constantly changing direction.
How did Rutherford infer that the nucleus was very small?
In conclusion... Rutherford's experiment involved a radioactive source emitting alpha particles (2 protons and 2 neutrons). The radioactive source was aimed at a thin sheet of gold. The main observation made was that a few alpha particles were repelled back the way they had come, and this was not expected. This was because the positively charged alpha particles (2 protons), by the laws of electrostatic repulsion, were repelled by the positively charged nucleus of the atoms in the gold. He then made the final conclusion of that the small nucleus of an atom is central, has a large mass and positive charge. So yes, the nucleus is small compared to the size of an atom, however it was mainly the fact that there is one concentration of positive charge (nucleus) in the atom that repelled the alpha particles that helped Rutherford to show the structure of an atom.
In Rutherford's gold foil experiment particles in dense atomic nuclei caused some alpha particles to bounce straight back from the gold foil.?
positive
Why the alpha particles pass through the foil unaffected?
Alpha particles have high energy but relatively low charge density, so they interact weakly with the electrons in the atoms of the foil. Additionally, the majority of an atom is empty space, so most alpha particles pass through the foil without colliding with the nucleus. Only a few alpha particles are deflected or bounce back due to a direct hit on the positively charged nucleus of an atom in the foil.
Why can you see using light?
The sensors in the back of your eyes detect light particles that bounce off the thing you're looking at.
What causes a basketball to bounce?
Well ya see when it goes down it comes back up. Repeatedly
