either of a pair of elementary particles that have electric charges and magnetic moments of opposite sign and are the same in all other properties, such as mass, lifetime, and spin, e.g., the electron and positron. Every particle has an antiparticle.
In particle physics, every type of particle of "ordinary" matter (as opposed to antimatter) is associated with an antiparticle with the same mass but with opposite physical charges (such as electric charge). For example, the antiparticle of the electron is the positron (also known as an antielectron).
antiparticle, subatomic particle having the same mass as one of the particles of ordinary matter but opposite electric charge and magnetic moment. Thus, the positron (positively charged electron) is the antiparticle of the negatively charged electron.
Antiparticle can be defined as a subatomic particle having the same mass as a given particle but opposite electric or magnetic properties. Every subatomic particle has a corresponding antiparticle. Figure 1 shows some of the particles and their antiparticles.

Every particle has an antiparticle. Antiparticles have the same mass and rest energy but are oppositely charged. They are usually labelled with a line over the top of their symbol. The antiparticle of the proton is the antiproton. It has the same mass (1.67×10 -27 kg) and rest energy (938 MeV) as a proton.
There is an associated antiparticle in particle physics, corresponding to most kinds of particles. An antiparticle has the same mass and opposite charge (including an electric charge). For example, there is a corresponding type of antiparticle for every quark.
