Wharton, “ Laboratory electron … Web20 aug. 2006 · An electron is negatively charged while the positron is positively charged (electrons are sometimes called negatrons to differentiate them from positrons). The important thing about positrons is that when they encounter electrons, they annihilate in bursts of light called gamma rays.
The positron or antielectron is the antiparticle or the antimatter counterpart of the electron. It has an electric charge of +1 e, a spin of 1/2 (the same as the electron), and the same mass as an electron. When a positron collides with an electron, annihilation occurs. If this collision occurs at low energies, it … Meer weergeven Theory In 1928, Paul Dirac published a paper proposing that electrons can have both a positive and negative charge. This paper introduced the Dirac equation, a unification of quantum … Meer weergeven Positrons are produced, together with neutrinos naturally in β decays of naturally occurring radioactive isotopes (for example, potassium-40) and in interactions of gamma quanta (emitted by radioactive nuclei) with matter.

Positrons are what we call the anti-particle to the electron. They have the same mass, but opposite electric charge. When a positron and electron meet, they can annihilate, destroying both and converting their mass energy into two photons (or Z bosons, at high enough energy). This is why we don't see positrons very often.
