→About the Binding Energy of a Nucleus
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 the Binding Energy of a Nucleus===
*[[Binding Energy|Binding energy]] = [[Mass Defect|mass defect]] × [[Speed of Light|c²c]]².
*[[Binding Energy|Binding energy]] [[measure]]d in [[MeV]].
*[[Binding Energy|Binding energy]] indicates the stability of the [[Atomic Nucleus|nucleus]] with a higher [[Binding Energy|binding energy]] indicates indicating a more stable [[Atomic Nucleus|nucleus]].*[[Binding EnergyPer Nucleon|'''Binding energy''' per nucleon]] represents the [[energy]] required to disassemble a [[Atomic Nucleus|nucleus]] into individual [[nucleon]]s.*Higher [[Binding Energy Per Nucleon|'''binding energy''' per nucleon]] implies a more stable [[Atomic Nucleus|nucleus]].
*The curve of [[Binding Energy Per Nucleon|'''binding energy''' per nucleon]] versus [[mass]] number shows a peak at [[iron]] (Fe-56).
===Examples===
*[[Helium]]-4 has a high [['''Binding EnergyPer Nucleon|''' Per Nucleon|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]].
