The nucleus of an atom takes up only a small fraction of the total space occupied by an atom. Most of the space is occupied by the electron cloud, where the comparatively massive alpha particles (helium nuclei) were virtually unaffected by their passage, even if they collided with many electrons.
What else can I help you with?
In Rutherfords gold foil experiment particles in dense atomic nuclei caused some alpha particles to bounce straight back from the gold foil.?
positive
What will happen if you use beta particles on gold foil?
If the alpha particles hit the gold foil most of the alpha particles will pass through the gold foil because atoms mostly consists of empty space and some alpha particles will be deflected including a very small number of alpha particles will bounce back in the direction they came from because the atom has a very small positively charged mass called the nucleus.
If Rutherford made bombarded aluminum foil with alpha particles instead of gold foil what observations would he have used?
The scattering angles would have changed, but the qualitative results would also change: the reason Rutherford chose gold was because it is EXTREMELY malleable. One can stretch gold foil until it is only a few atoms thick in places, which is not possible with aluminum. If the foil were too thick, there would be no transmission of particles at all; the whole point was to demonstrate that most alpha particles passed through unchanged, but some of them scattered, which is only possible with a VERY thin foil.
Why Rutherford does not use beta particles for scattering on gold foil?
Rutherford did not use beta particles for scattering experiments on gold foil because beta particles, being charged electrons, would have been deflected significantly by the electric fields of the atomic nuclei. Instead, he used alpha particles, which are positively charged and much heavier, allowing for a more straightforward interpretation of their scattering patterns. The interactions of alpha particles with the gold foil provided clearer insights into the structure of the atom, leading to the discovery of the nucleus. Additionally, alpha particles have a higher energy, which enhances their ability to penetrate the foil.
How did the gold foil experiment prove an atom was mostly empty space?
In the gold foil experiment by Rutherford, most alpha particles passed through the gold foil, indicating that atoms are mostly empty space. The few particles that were deflected showed that the positive charge of the atom is concentrated in a small, dense nucleus, which explains why most of the particles passed through without being deflected.
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 Rutherford's gold foil experiment what particles were fired at a thin piece of gold?
I believe they are called the Alpha particles and yes, they did pass through a sheet of gold foil.
What materials are needed for rutherfords gold foil experiment?
For Rutherford's gold foil experiment, you will need the following materials: thin gold foil, alpha particles, a source for the alpha particles, a fluorescent screen or detector to observe the scattered particles, and a vacuum chamber to prevent air molecules from interfering with the experiment.
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.
What caused the deflection of the alpha particles in Rutherfords gold foil experiment?
A zinc sulfide coated screen surrounding the gold foil produced a flash of light whenever it was struck by an alpha particle. By noting where the flash occurred, the scientists could determine if the atoms in the gold foil deflected the alpha particles.
In Rutherfords gold foil experiment particles in dense atomic nuclei caused some alpha particles to bounce straight back from the gold foil.?
positive
What was rutherfords experiment?
he shot tiny alpha particles throug a piece of gold foil. -Apex
Why does sodium foil result with fewer alpha particles compared to gold foil?
Sodium nuclei are much smaller than gold nuclei. Therefore, more alpha particles will hit the larger nucleus of gold because it is a much bigger target.
What did Rutherford observed that surprise him?
Most of the alpha particles shot at the gold foil went straight through the foil.
Where did most of the alpha particles fired at the foil go in the gold foil experiment?
Most of them went right through.
Why is gold foil used in the alpha particle scattering?
Hi I believe the answer to be because of its high density. Gold or Aurum (Au) is very dense and hence will 'reflect'and 'deflect' alpha particles, which are helium nuclei. Beta particles are electrons Hope that helps
What happened to the alpha particles as they hit the gold foil?
They stop.
