What is called the antiparticle for a given particle? Give examples of particle-antiparticle pairs.

When a particle collides with its antiparticle, they annihilate. In this case, other particles appear. Examples of pairs of a particle and its antiparticle are an electron and a positron, a proton and an antiproton. A particle differs from an antiparticle only in one of the many quantities characterizing them.
