Beta particle( electron having nuclear origin) is emitted when a neutron decays into a proton by giving out electron. The electron produced escapes as a beta particle leaving proton in the nucleus of atom. 0n1 --> 1p1 + -1e0 ( 1e0 is the emitted beta particle) here subscripts denote charge and superscript denote mass in atomic mass unit(amu). Such neutron decay are shown by some radioactive elements. Usually when the n/p (neutron/proton) ratio is higher than required nuclei emit beta particle. Many examples of this type of decay can be given like: 6c14 --> 7N14 + -1e0 (this carbon isotope is used in carbon dating). 90Th232 + 0n1 --> 90Th232 - -1e0 --> 91Pa233 - -1e0 --> 92U233 (this reaction is used in breeder reactors for production of fissile uranium isotope)
The energy of the beta particle ejected from a nucleus undergoing beta decay varies widely. It can range from a few keV to something on the order of 1 MeV. The latter can see the beta particle moving at ultrarelativistic speeds, which means near the speed of light. This is the exception rather than the rule, however. The range of the particles in air is a few meters to a few tens of meters, depending on energy. A sheet of aluminum foil is a good beta particle stopper, and "normal" clothing will block almost all of them.
Well, that's kinda a trick question because an electron is pure energy. An electron particle is also the smallest of the 4, so its the electron (eventhough an electron is a weichtless particle such as a graviton or magneton! Hope I helped!!

Thorium 234: Beta decay. Atomic number increases by 1.
A beta particle is a high energy electron. An alpha particle is a helium nucleus. A gamma ray is a high energy photon.
Beta is a particle. In beta- it is an electron and an electron antineutrino. In beta+ it is a positron and an electron neutrino.
There is only one type of alpha particle - a helium-4 nucleus. A beta particle can either be an electron or an anti-electron. However, consulting the Wikipedia article "Isotopes of silver", it seems that silver-111 has a beta-minus decay - that means that it emits a regular electron (which has a negative charge).
I think it is also known as an electron.... Hope this helps.
A beta particle is either an electron or an anti-electron (aka positron).
A beta particle is either an electron, or a positron (aka "anti-electron").
The alpha particle is much more massive than a beta particle. A beta particle is an electron, which has very little mass. An alpha particle is a helium nucleus, and consists of two protons and two neutrons.
A alpha particle is a helium-4, written 24He, nucleus, and it is composed of a pair of protons and a pair of neutrons fused together. It's charge is +2. A beta particle could be either a beta + particle, which is a positron, or a beta - particle, which is an electron. The electron (beta -) has a charge of -1, and the positron (beta +) has a charge of +1. In summary, the alpha is +2, the beta minus is -1, and the beta plus is +1.
The alpha particle basically has the mass of a helium atom, since it is a helium nucleus. The beta particle has the mass of an electron - a beta particle is either an electron or an anti-electron. The gamma ray has no rest mass, since it moves at the speed of light. However, it can have a fairly high energy, and therefore an associated mass. The mass varies in this case; that is, gamma rays can have different energies, and therefore different masses.
A beta particle can be an electron, or a positron (anti-electron).
There is one electron in a beta- particle, because a beta- particle is an electron and an electron antineutrino. A beta+ particle is a positron and an electron neutrino. A link can be found below to a related question that will help a bit in sorting out the puzzles surrounding beta particles.
The beta particle is an electron.
