Antiparticle (noun)

A subatomic particle that has the same mass as a particle of matter but has opposite electric charge and other differences in quantum properties.

Origin:

From the prefix "anti-" meaning "opposite" and the word "particle" meaning "a tiny piece of matter".

Examples:

  1. The antiparticle of the electron is the positron.
  2. Antiparticles have the same mass as particles of matter but have opposite charges.
  3. Antiparticles play a major role in the behavior of subatomic particles.
  4. Antiparticles are important in the study of particle physics.
  5. The existence of antiparticles was first predicted by Paul Dirac in 1928.
