Among other things, they are the result of nuclear reactions. Thus, they can be artificially created. Some very high-energy gamma rays come from outer space; it is not always clear how they are created, although it is commonly believed that at least some of them are the result of the creation of black holes.

∙ 11y agoThe cause of beta emission is an excess number of neutrons in the atomic nucleus. When there are significantly more neutrons than protons in a nucleus, the neutrons degenerate into protons and electrons (Beta particles), which are ejected from the nucleus at high speeds. This increases the atomic number of the atom and also increases its stability, an example of natural atomic alchemy which gives rise to a new type of atom.

It is actually an electron.

What type of particles are released as part of beta decay?
The "beta decay" is named after the type of particles emitted - beta particles.A beta particle is either an electron, or an anti-electron (a.k.a. "positron").
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.
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 correctly describes the charge of beta particles and alpha particles?
Beta particles, from beta- decay, have a charge of -1. Beta particles, from beta+ decay, have a charge of +1. Alpha particles have a charge of +2.
How beta particles are emitted from nuclei as there are no electrons in nucleas of an atom than from where beta rays are emmited?
nucleus is a very complicated region and we known little about thattheoretically a neutron is broken down to a proton and a beta particle during radioactivity so with in nucleus beta particle is a part of neutron.
What is the range of beta particles in the air?
The range of beta particles in the air is up to several hundred feet. Beta particles are emitted by specific types of radioactive nuclei. Potassium-40 is a type of radioactive nuclei that emits beta particles.

What happens when U-235emits a beta particle?
U-235 emits beta particles as part of typical radioactive decay. When a beta particle is emitted, an electron is emitted and a neutron is converted into a proton.
Are beta particles positive or negative?
Beta particles can be either positive or negative. It depends if an electron or a positrion is emited. Usually though, beta particles are negative as it is much more common for an electron to be emitted (though that does depend on the substance).
How many alpha particles are produced as one atom of uranium-238 decays to an atom of lead-206?
4 alpha particles were emitted. This is known by the fact that an alpha particle ,on being given out, decrease the mass number of the element by 4.Hence the decrease in mass number in above question is 12 which itself states the answer that 4 alpha particles are emitted. The number of beta particles emitted are 3 beta particle have been emitted.
What is one unique fact about beta particales?
Beta particles are electrons, generally emitted by the cathode of a glow discharge system. When beta particles was discovered the atomic model was not known and the new "rays" were called with progressive names alfa rays, beta rays, gamma rays and so on.
What happens to polonium when beta particles are emitted?
The beta minus decay of polonium isotopes is extremely rare. Beta decay involve the increase of the atomic number with 1.Example: Po-218----------------beta minus---------------At-218

What is the energy of beta particle?
The end point energy of a beta decay is the kinetic energy of all particles emitted through B-decay. This is often ignoring the energy of the recoiling daughter nucleus.
What particle is emitted in beta radiation?
In unstable neuclei where there are 'too many' neutrons, a neutron will convert to a proton and an electron - that electron is ejected from the nucleus and is called a beta particle. It is important that we call this electron a beta particle because it is derived by radioactive disintegration in the nucleus and not an 'orbital' electron.

Will electrons will be emitted in a radioactive decay?
It does not usually involve the atom's electrons, except for a type of decay called K capture. But the beta particles ejected in what is called beta decay are either electrons or positrons.
