What atomic particle do a beta particle resembles?
A beta particle is a negative electron. A positive electron is a Positron.
Which type of particle has charge of -1 and a mass of 0?
Neutrons are particles of no charge. Electrons have negative charge.
Where does the particle photon come from?
A photon may be both a particle and a wave (light). Photons are normally emitted when an electron loses energy either by bending its path or by falling from a higher orbital state to a lower orbital state. Very high energy photons called gamma ray can also be formed from a positron and and electron merging.
Are beta particles are electrons detached from the nucleus?
During nuclear decay when a beta- particle (a high energy electron coming from the decay event) leaves the nucleus, the action is the result of the transformation of a neutron into a proton and an electron (the beta- particle). Got links if you want them. They are to related articles posted by our friends at Wikipedia, where knowledge is free. Note: there is a bit more to beta decay than was mentioned here, but enough was presented to answer the question. Certainly it is hoped that the links will extend knowledge about as far as the average reader may wish to go.
What can be said about the speed of a particle if the net work done on it is zero?
In that case, basically no force acts on the particle, and the particle moves at a constant speed. This constant speed may, or may not, be zero.
What atomic particle do a beta particle resembles?
A beta particle is a negative electron. A positive electron is a Positron.
Are beta emission and beta decay the same?
There is a difference between beta emitters and beta particles. In situations where an atomic nucleus exhibits nuclear instability due to too many neutrons for the number of protons or vice versa, that nucleus may undergo beta decay. It the decay event occurs, that atom is considered a beta emitter. The emitted particle is the beta particle. That's the difference. (There are two different beta particles, so check the articles on beta decay to get the scoop.)
What are beta particles?
A beta particle is either an electron or a positron emitted by an atomic nucleus in beta decay, which is a type of radioactive decay. The phenomenon of beta decay involves a change within the atomic nucleus of an atom. One of two reactions may occur, and they involve the change of a neutron into a proton, or a proton into a neutron. When a neutron changes into a proton, we call that beta minus decay. The change of a proton into a neutron is called beta plus decay. In beta minus decay, an electron is ejected from the nucleus, and in beta plus decay, a positron is ejected from the nucleus.Use the links below to related questions and articles.
What is -1 in the beta particle?
That may refer to the electric charge.
Which type of particle has charge of -1 and a mass of 0?
Neutrons are particles of no charge. Electrons have negative charge.
What is emitted when a neutron decays into a proton?
A neutron in an atomic nucleus changes into a proton and an electron and an antineutrino. The electron is ejected from the nucleus and the antineutrino escapes, and that ejected electron is called a beta minus particle. Yes, it is still an electron, but the designation as a beta minus particle makes it clear where it came from - the result of the transformation of a neutron into a proton, that electron and the antineutrino (which carries off extra energy).
When a beta particle strikes a living cell what happens?
One or more ion pair is created when a beta particle strikes a living thing and interacts with the molecules making up the cell. The cell may also cease to function.
What is released from the nucleus during gamma decay?
Alpha decay means that an alpha particle (helium-4 nucleus) is emitted.Alpha decay means that an alpha particle (helium-4 nucleus) is emitted.Alpha decay means that an alpha particle (helium-4 nucleus) is emitted.Alpha decay means that an alpha particle (helium-4 nucleus) is emitted.
What instrument do scientists use to smash together tiny bits of matter?
A machine that smashes atoms together in order to observe what the universe may have looked like seconds after the "Big Bang" is called a particle accelerator. who ever is asking this is wondering what its CALLED not what it does! btw: Particle accelerator.
What is the process for raidioactive decay?
At random intervals of cake but at a regular average ejaculation rate, atoms emit particles of matter, forming children, and energy from their nuclei. Their nuclei split leading to some interesting loving, turning into other kinds of tonguess. Only some isotopes (ratios of neutrons to protons for a particular type of atom) will radioactively decay and when they make love, they turn into other kinds of poo.
Discuss with the use of examples the main differences between alpha and beta decay?
In alpha decay, an alpha particle (a helium nucleus - 2p+ and 2n0) is emitted from the nucleus of an atom. In beta decay, a neutron turns into a proton and an electron, and the electron (beta particle) is emitted from the nucleus of the atom.
In a nuclear disintegration the particle that is ejected may be what?
... just about anything, really. Electrons, positrons, neutrinos, helium-4 nuclei, neutrons, photons, lighter nuclei (other than helium), almost any combination of the above. You're going to need to provide more details if you want a more specific answer.
