==Key Stage 5==
===Meaning===
'''Strangeness''' is a [[Conservation of Strangeness|conserved quantity]] in the [[Strong Nuclear Interaction|strong nuclear interaction]] but is not [[Conservation of Strangeness|conserved]] in the [[Weak Nuclear Interaction|weak interaction]].
===About Strangeness===
: '''Strangeness''' is carried by the [[Strange-quark]], which carries a '''strangeness''' of -1 and the [[Antistrange-quark]], which carries a '''strangeness''' of +1.
: During the [[Strong Nuclear Interaction|strong interaction]] '''strangeness''' is transferred between [[hadron]]s.
: During the [[Weak Nuclear Interaction|weak interaction]] a [[Strange-quark]] may [[Radioactive Decay|decay]] into a [[Down-quark]] losing its '''strangeness'''. Similarly an [[Antistrange-quark]] may [[Radioactive Decay|decay]] into an [[Antidown-quark]].
: [[Baryon]]s may carry a '''strangeness''' of between -3 (for [[matter]]) and +3 (for [[antimatter]]).
: [[Meson]]s may carry a '''strangeness''' between -1 and 1.
