==Key Stage 5==
===Meaning===
'''Antimatter''' is a [[material]] made from [[antiparticle]]s, which when in contact with [[matter]] will [[Annihilation|annihilate]] one another to produce a pair of [[photon]]s.
===About Antimatter===
: Many [[Subatomic Particle|particle]]s of [[matter]] have '''antimatter''' counterparts which have the same [[mass]] but opposite [[Electrical Charge|electrical charge]].
: During [[Pair-Production|pair-production]] a [[Subatomic Particle|particle]] and its '''antimatter''' counterpart appear.
: Most '''antiparticles''' are given the name of their counterpart [[Subatomic Particle|particle]] with the addition of the prefix '''anti'''. However, the '''antiparticle''' counterpart of the [[electron]] is known as the [[positron]].
