Common questions
What is the Nuclear Binding Energy formula?
Nuclear Binding Energy is written E_b = Δm · c² = [Zm_p + Nm_n − M]c². Energy required to disassemble a nucleus into separate nucleons. It belongs to Modern Physics, under Nuclear Physics.
What are the units in E_b = Δm · c² = [Zm_p + Nm_n − M]c²?
In SI units, E_b is binding energy, measured in J; Δm is mass defect, measured in kg; Z is number of protons (dimensionless); N is number of neutrons (dimensionless); m_p is proton mass, measured in kg; m_n is neutron mass, measured in kg; M is nuclear mass, measured in kg.
