Nuclear Mass Defect (Δm) & Binding Energy per Nucleon Calculator
Calculate isotopic nuclear mass defect (amu), total binding energy (MeV), and binding energy per nucleon (MeV/nucleon) using Einstein's mass-energy equivalence.
Binding Energy per Nucleon (MeV/nucleon)
Calculator Inputs
Binding Energy per Nucleon (MeV/nucleon)
Nuclear Mass Defect (Δm in amu)
Total Binding Energy (MeV)
Free Nucleons Mass
Exceptional Nuclear Stability: Binding energy exceeds 7 MeV per nucleon, indicating tight subatomic cohesion against spontaneous decay.
Nuclear Binding Energy & Stability Profile
Standard nuclear chemistry and modern subatomic physics tool for isotopic stability curves.
Calculation Methodology
Mass Defect Equation: Δm = (Z * m_p + N * m_n) - M_actual. Where proton mass m_p = 1.007276 amu, neutron mass m_n = 1.008665 amu. Total Binding Energy: BE = Δm * 931.494 MeV. Binding Energy per Nucleon: BE/A = BE / (Z + N).
