In rutherfords gold foil experiment what particle in dense atomic nuclei caused so alpha particles to bounce straight back from the gold foil?
In Rutherford's gold foil experiment, the alpha particles were deflected back primarily due to the presence of densely packed positive charge concentrated in the atomic nucleus, specifically due to protons. When the high-energy alpha particles, which are positively charged themselves, approached the nucleus, they experienced strong electrostatic repulsion from the protons, causing them to bounce back. This unexpected deflection provided crucial evidence that atoms have a small, dense nucleus at their center, leading to the development of the nuclear model of the atom.

In Rutherfords gold foil experiment particles in dense atomic nuclei caused some alpha particles to bounce straight back from the gold foil.?
positive
How did the number of particles that followed a straight path compare with the number deflected?
In experiments involving particle collisions, the number of particles that followed a straight path is typically greater than the number that were deflected. This is because most particles pass through the region without interacting with other particles or obstacles. Deflections occur primarily due to interactions with other particles or forces, which are less frequent than straight-path trajectories. Thus, while a significant number may be deflected, the majority generally continue in a straight line.
What 3 ways do particles in gas move?
Particles in gas move in a straight line until they collide with another particle or the walls of the container. They move at a constant speed until they collide, then change direction. The particles have random motion, moving in all directions.
In Rutherford and gold foil experiment particles in dense atomic nuclei caused some alpha particles to bounce straight back from the gold foil.?
In the Rutherford gold foil experiment, alpha particles were directed at a thin sheet of gold foil. Most of the particles passed through, but some were deflected at large angles, and a few even bounced straight back. This unexpected behavior indicated that the atom has a dense, positively charged nucleus, which contains most of its mass, leading to the conclusion that atoms are mostly empty space with a small, concentrated core. This finding revolutionized the understanding of atomic structure, establishing the nuclear model of the atom.
Describe Rutherford's experiment on scattering of alpha particles. what are its consequences?
Rutherford's experiment involved firing alpha particles at a thin gold foil and observing their scattering patterns. Most particles passed straight through, but some were deflected at large angles, leading to the conclusion that an atom's mass and positive charge are concentrated in a small nucleus, rather than being evenly distributed as previously thought. This experiment overturned the plum pudding model of the atom, leading to the nuclear model and laying the groundwork for modern atomic theory. Its consequences included a deeper understanding of atomic structure and paved the way for future discoveries in nuclear physics.
In Rutherfords gold foil experiment particles in dense atomic nuclei caused some alpha particles to bounce straight back from the gold foil.?
positive
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
Which describes the path of a gas particle between collisions with other particles?
Straight line
Rutherfords gold foil experiment led to the discovery of the?
Nucleus - Rutherford fired particles at gold foil, and most went straight through. This showed that most of atoms are empty, and that most of the mass only occupies a small part of the atom. This part is known as the nucleus.
What feature of rutherfords gold foil experiment was most surprising to those who carried out the experiment?
The most surprising feature of Rutherford's gold foil experiment was the discovery that some alpha particles were scattered at very large angles, even back towards the source. This suggested that the positive charge in an atom was concentrated in a small, dense nucleus, rather than being spread out as previously thought.
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.
What feature of rutherfords gold foil expirement was most surprising to those who carried out the expirement?
Some alpha particles deflected, some went straight through and come were deflected.
Which particle was discovered during the gold foil experiment?
The discovery of the atomic nucleus was made during the gold foil experiment by Ernest Rutherford in 1909. He observed that most of the alpha particles passed straight through the gold foil, indicating that atoms have a small, dense nucleus at their center.
What are the main ideas of e Rutherford gold foil experiment?
basically, Rutherford shot postively charged particles at a thin sheet of gold foil. most of the particles passed straight through, but some bounced off at sharp angles. This implies that most of the atom is empy space (which is why most of the particles go straight throught) , but there is a positively charged nucleus at the center (which repels the postively charged particles, so if a particle hits the nucleus, it bounces off )
If a particle hits a gold nucleus in a head-on collision?
If a particle hits a gold nucleus in a head-on collision, the two would come to a rest for a very brief moment and then the particle would bounce straight back. This is describing a hypothetical situation proposed for Rutherford's gold foil experiment where he confirmed a small positively charged nucleus was present in atoms.
Would particles pass straight through gold foil?
No, most particles would not pass straight through gold foil. Gold is a dense material that effectively blocks or deflects particles like alpha particles due to its high atomic number and density. This property is the basis for Ernest Rutherford's gold foil experiment which led to the discovery of the atomic nucleus.
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.
