Free Binding Energy per Nucleon Calculator
Calculate the total binding energy and binding energy per nucleon from the mass defect of a nucleus.
Total Binding Energy
492.20 MeV
Total Binding Energy vs Mass Defect (delta m)
Nuclear Binding Energy
The binding energy is the energy required to disassemble a nucleus into free protons and neutrons. Higher binding energy per nucleon means greater nuclear stability.
Formula
BE = delta_m × 931.494 MeV/u
BE per nucleon = BE / A
where delta_m is the mass defect (in atomic mass units) and 931.494 MeV/u is the energy equivalent of one atomic mass unit. Iron-56 has the highest BE/nucleon at about 8.79 MeV.
Example Calculation
Fe-56 with mass defect 0.5284 u and A = 56 nucleons.
- 01BE = 0.5284 × 931.494 = 492.3 MeV
- 02BE/A = 492.3 / 56 = 8.79 MeV/nucleon
