When potassium-39 is bombarded by neutrons chlorine-36 is produced what other particles are emitted?
An Alpha particle
Can you give me the advantages available to the gamma rays to be used in the field of radiography compared with alpha particles and beta particles?
alpha is stopped by a sheet of paperbeta is stopped by a sheet of foil or a couple inches of other materialgamma penetrates long distances
What stops alpha decay?
Alpha decay cannot be stopped. It is an energy release process that only ends when the parent nuclide decays to zero.If you mean, however, "what stops alpha particles?", then the answer is a few inches of air, a sheet of paper, your skin, etc. This is because alpha particles are heavy, with an atomic mass number of four, and charged, with an atomic charge of +2; as a result, they interact with other matter very, very easily.Normal protection from alpha particles, say when handling new uranium-235, can be as simple as a pair of gloves. The problem with alpha particles comes when you ingest the material that creates them, placing the alpha particles in close proximity to sensitive tissues inside your body. That makes alpha particle emitting material very hazardous, if not properly contained.
Why did Rutherford conclude that an atoms nucleus has a posotive charge instead of a negative charge?
when carrying out the alpha scattering experiment, he observed that some alpha particles got deflected from their course. as alpha particles are helium nuclei, they are positively charged. the fact that they deviate made him think that there might be some repulsion between the particles and the nucleus. as positive charges repel each other, he determined the nucleus to be positively charged.
When curium 242 is bombarded with alpha particles two products are formed one of these is a neutron what is the other?
I suppose that the isotope formed is Am-245.
Is it possible to clone alpha particles?
No. You can produce alpha particles in a number of ways, but that's not really "cloning" as the term is usually used, even if all alpha particles are indistinguishable from each other.
What element does an atom of polonium change into after it emits an alpha particle?
Polonium 210-----------alpha particles-----------Lead 206 Polonium 209-----------alpha particles-----------Lead 205 Polonium 208-----------alpha particles-----------Lead 204 Polonium 214-----------alpha particles-----------Lead 210 Polonium 218-----------alpha particles-----------Lead 214 (99,98 %) Polonium 218-----------beta particles------------Astatin 218 (o,o2 %) For other isotopes see the list at: http://en.wikipedia.org/wiki/Polonium#Isotopes
What happened to the alpha particles as they hit the gold foil?
They stop.
What causes some of the alpha particles to bounce straight back from the gold foil?
Alpha particles are composed of two neutrons and two protons, so they have a positive charge. When the alpha particles bounced straight back from the gold foil, this indicated that they had hit a particle of like charge, in other words a positively charged particle in the gold foil, which repelled the alpha particle.
Do nuetrons have higher mass or alpha particles?
alpha particles consist of two protons and two neutrons (helium nucleus) logically one neutron can not have a larger mass than two neutrons and two other subatomic particles of a similar mass
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 Rutherford know the nucleus was positively charged?
the nucleus is positively charged because it bounces right off of the gold foil
When potassium-39 is bombarded by neutrons chlorine-36 is produced what other particles are emitted?
An Alpha particle
Alpha particles are repelled by atomic nuclei because?
Alpha particles are repelled by atomic nuclei because alpha particles have a positive charge, and so do atomic nuclei. The positive charge on the surface of a nucleus will repel another positive charge, like an alpha particle, because of the law of electrostatics. That's the simple answer. And it is correct. But know this: Alpha particles were used in the early investigations of atomic structure and atomic interactions. The alpha particles were used to bombard atomic nuclei, and there are times when an alpha particle will be absorbed by an atomic nucleus. Somehow the laws of electrostatics took the day off, and the fact that absorption took place opens the door to discovery and discussion of other atomic forces. Word up.
Why did the path of only some alpha particles deviate in Rutherford experiment?
Alpha particles are positively charged helium nuclei. As such, they are repelled by other positively-charged nuclei. In Rutherford's experiment, he used gold foil. Since gold atoms have large, massive nuclei, the alpha particles were easily repelled by the large gold atom nuclei, and they were scattered in different directions.
