Binding energy of atomic nuclei. Mass defect
Lesson 3: isotopes. The nucleus mass is less than the sum of free proton and neutron masses → mass defect . By (Einstein) this 'missing' mass is the binding energy.
Lesson 3: isotopes. The nucleus mass is less than the sum of free proton and neutron masses → mass defect Δm. By E=Δm⋅c2 (Einstein) this 'missing' mass is the binding energy.
