==Key Stage 5==
===Meaning===
The [[Binding Energy|binding energy]] of a [[Atomic Nucleus|nucleus]] is the work that must be done to separate a [[Atomic Nucleus|nucleus]] into its constituent [[neutron]]s and [[proton]]s.
===About Binding Energy of a Nucleus===
*[[Binding Energy|Binding energy]] = [[Mass Defect|mass defect]] × [[Speed of Light|c²]].
*[[Binding Energy|Binding energy]] [[measure]]d in [[MeV]].
*Indicates the stability of the [[Atomic Nucleus|nucleus]].
*Higher binding [[energy]] per [[nucleon]] implies a more stable [[Atomic Nucleus|nucleus]].
The curve of [[Binding Energy|binding energy]] per [[nucleon]] versus [[mass]] number shows a peak at [[iron]] (Fe-56).
===Examples===
*[[Helium]]-4 has a high [[Binding Energy|binding energy]] per [[nucleon]], making it very stable.
*[[Nuclear Fusion|Nuclear fusion]] and [[Nuclear Fission|fission]] involve changes in [[Binding Energy|binding energy]], releasing [[Energy|energy]].
