Key Stage 5
Meaning
Antimatter is a material made from antiparticles, which when in contact with matter will annihilate one another to produce a pair of photons.
About Antimatter
- Many particles of matter have antimatter counterparts which have the same mass but opposite electrical charge.
- During pair-production a particle and its antimatter counterpart appear.
- 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.
