दिया है: प्रोटॉन का द्रव्यमान `(m_(p))=1.007834`
न्यूट्रॉन का द्रव्यमान `(m_(n))=.00867u`
`._(7)^(14)N` नाभिक में 7 प्रोटॉन तथा 7 न्यूट्रॉन है।
द्रव्यमान क्षति `(Deltam)=` न्यूक्‍लिऑन का द्रव्यमान `-` नाभिक का द्रव्यमान
`=7m_(p)+7m_(n)-m_(N)`
`=7xx1.00783+7xx1.00867-14.00307`
`=7.05481+7.06069-14.00307=0.11243u`
नाइट्रोजन के नाभिक की बंधन ऊर्जा `=Deltamxx931MeV`
`=0.11243xx931MeV`
`=104.67MeV`
अतः बंधन ऊर्जा `104.67MeV` है।
