Nuclear Binding Energy Calculator

Calculate binding energy and stability using E=mc²

Mass Number (A):

Atomic Number (Z):

Measured Atomic Mass (u):

Quick Presets:

Mass Defect: Delta m = Z*m_p + N*m_n - M_nucleus

Binding Energy: E_B = Delta m * c^2 = Delta m * 931.494 MeV/u

Binding Energy per Nucleon: E_B/A

The most stable nuclei (Fe-56, Ni-62) have the highest binding energy per nucleon (~8.8 MeV).
