Positron. Electrón with load positive. Interaction with the electron can result in the annihilation of both, resulting in a pair of photons whose energy equals the mass of the electron-positron pair. This property defines the positron as the antiparticle associated with the electron

It is the antiparticle corresponding to the electron, so it has the same mass and electric charge (although with a different sign, since it is positive). Not part of the ordinary, but of matter antimatter , although numerous processes occur in chemical Radio as part of nuclear transformations.
The antielectron is as stable as the electron, in fact it is identical to the electron in all its aspects except its electrical charge. Its existence can be indefinite. Although the average life span is one millionth of a second, until it meets an electron, during a flashing moment the electron and the positron were associated; both particles rotate around a common center of force.
But the existence of this system, at most, will last a ten millionth of a second since the positron and the electron combine. When the two opposite particles combine, a mutual neutralization occurs and they literally disappear, leaving no trace of matter (mutual annihilation). But since matter is known, just as energy cannot disappear, as a result of this, energy remains in the form of gamma radiation . Just as the genius Albert Einstein had suggested : matter can be converted into energy, and vice versa.
When in the early universe photons were continually converted into a pair of positrons and electrons, and then these into photons.
The positron being an antiparticle corresponding to an electron, since this has the same electric charge and the same mass, (although of a different sign, since it is positive), with the opposite sign (positive).
This is not part of ordinary matter, it is part of antimatter, although it is produced in certain radioactive processes, it is part of nuclear transformations.
