Positron

The positron is an elementary particle and the anti-particle of the electron. Positrons can be mined from electron field blocks.

Positrons are the anti-particles of electrons. Therefore, when the electron and the positron touch each other, they disappear. All that is left is two photons. Because the electron and the positron are each others anti-particles, they have annihilated each other. The amount of energy created in this process is quite large: because of this, there are many references to antimatter bombs or weapons in popular culture.

Positrons have a positive electric charge. This is depicted by the small + on the face of the positron.

Because of the electric charge, positrons experience the Coulomb force from other objects with an electric charge. Just put some positrons in your world and watch them move away from each other.

Dive deeper into the Physics: positron
Positrons are the anti-particles of electrons. You could call positrons anti-electrons. Anti-particles are very similar to the particles, but all of their charges have the opposite sign. For example, the electron has an electric charge of -1 and the positron has an electric charge of +1.

When a particle and an anti-particle touch each other, they disappear in a flash of light. Physicists call this phenomenon annihilation.
