Key Stage 5
Meaning
Antiparticles are small units of anti-matter.
About Antiparticles
- Many particles of matter have antimatter counterparts which have the same mass but opposite electrical charge.
- During pair-production a particle and its antiparticle appear.
- When a particle meets its antiparticle they annihilate one another producing a pair of photons.
- Most antiparticles are given the name of their counterpart particle with the addition of the prefix anti. However, the antiparticle counterpart of the electron is known as the positron.
