==Key Stage 5==
===Meaning===
'''Neutrinos''' are [[Neutral Charge|neutral]] [[lepton]]s with negligible [[mass]].
===About Neutrinos===
: '''Neutrinos''' are very difficult to detect but they have been demonstrated to exist due to the law of [[Conservation of Momentum|conservation of momentum]] applied during [[Radioactive Decay|decay]] occurring due to the [[Weak Nuclear Interaction|weak interaction]]. During a [[Radioactive Decay|decay]] the observable products can be seen to move in such a way as would violate [[Conservation of Momentum|conservation of momentum]] showing that another [[Subatomic Particle|subatomic particle]] must be created in the [[Radioactive Decay|decay]].
: Due to their negligible [[mass]], [[neutrino]]s are very stable and pass through most [[matter]] without any interaction.
: '''Neutrinos''' released during [[Radioactive Decay|decay]] tend to travel at speeds approaching the [[Speed of Light|speed of light]].
: The evidence for '''neutrinos''' also reveals the [[Conservation of Lepton Number|conservation of lepton number]].
