some of alpha particles were deflected through an angle of 90 degree
What else can I help you with?
Why beta and alpha particles deflected when they pass the magnetic field?
Alpha and beta particles are deflected by a magnetic field because they have charge and, as such, are affected by the electromagnetic interaction or force.
When a beam of alpha particles passes between two electrically charged plates - which plate is the beam deflected toward?
The beam would be deflected to the negative plate, as alpha particles are Helium nuclei and are positively charged.
Why alpha particles is a threat to humans?
Alpha particles ARE not a threat to humans. They can be deflected by nothing more than a sheet of paper.
What happened to the alpha particles as they hit the gold foil?
They stop.
When a beam of alpha particles passes between two electrically charged plates which plate is the beam deflected toward?
The beam of alpha particles is deflected toward the negatively charged plate. This is because alpha particles are positively charged, and opposite charges attract each other.
What did Rutherford call the region that deflected the alpha particles?
Rutherford called the region in the gold foil experiment that deflected alpha particles the "nucleus." He discovered that the positive charge and most of the mass of an atom were concentrated in this small, dense region.
Why were very few alpha particles deflected?
While most alpha particles passed straight through the foil. A small % of them were deflected at very large angles, some even backscattered. Because alpha particles have about 8000x the mass of an electron and impacted the foil at very high velocitiesIn order for the alpha particles to be deflected by significant amounts, they must pass close to one or more nuclei in the foil. Since nuclei occupy only a very small fraction of the the volume of an atom, and the foil was very thin so it was not very many atoms thick, the likelihood of such close encounters was small and only a small fraction of the alpha particles were deflected by large angles.
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.
Why weren't all the alpha particles deflected in Rutherford experiment?
While most alpha particles passed straight through the foil. A small % of them were deflected at very large angles, some even backscattered. Because alpha particles have about 8000x the mass of an electron and impacted the foil at very high velocitiesIn order for the alpha particles to be deflected by significant amounts, they must pass close to one or more nuclei in the foil. Since nuclei occupy only a very small fraction of the the volume of an atom, and the foil was very thin so it was not very many atoms thick, the likelihood of such close encounters was small and only a small fraction of the alpha particles were deflected by large angles.
Which type of radiation is deflected from its oringinal path when it strikes an object?
Alpha radiation is deflected from its original path when it strikes an object due to interactions with the atoms of the material. Alpha particles have a larger mass and positive charge, making them more likely to interact and be deflected by the electrons in the material.
Why are beta alpha particles deflected when pass the magnetic field?
Beta particles are deflected in a magnetic field due to their electric charge. Beta particles are either negative (beta-) or positive (beta+) charged, so they experience a force when passing through a magnetic field, causing them to be deflected from their original path.
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.
