The reaction is as follows: Only one of several product sets is shown.A few neutrons are always emitted in fission of this isotope, a feature essential to chain reactions.The process continues until a stable nuclide has been formed.positron, is the antiparticle of the electron; when brought together, two such particles will mutually annihilate each other.Gamma rays are electromagnetic radiations such as radio waves, light, and X-rays.Radioactivity, property exhibited by certain types of matter of emitting energy and subatomic particles spontaneously.It is, in essence, an attribute of individual atomic nuclei.Beta radioactivity also produces the neutrino and antineutrino, particles that have no charge and very little mass, symbolized by ν and of the parent nucleus.Neutrons and protons are, of course, the basic building blocks of complex nuclei, having approximately unit mass on the atomic scale and having zero charge or unit positive charge, respectively. It is rapidly captured by nuclei in matter; otherwise, in free space it will undergo beta-minus decay to a proton, an electron, and an antineutrino with a half-life of 12.8 minutes.

This orbital electron ejection is known as second).

With a few electron-capturing nuclides, it has been possible to measure directly the decay energy by measurement of a rare process called inner bremsstrahlung (braking radiation).

In this process the energy release is shared between the neutrino and a gamma ray.

An example is the decay (symbolized by an arrow) of the abundant isotope of In beta-minus decay, an energetic negative electron is emitted, producing a daughter nucleus of one higher atomic number and the same mass number.

An example is the decay of the uranium daughter product thorium-234 into protactinium-234: In the above reaction for beta decay, photons and are without rest mass or charge.
