    The difference between the mass of an atomic nucleus and the sum of the masses of its individual protons and neutrons.

    zh质量亏损

    • The mass defect is converted into binding energy according to Einstein's equation.
    • Scientists calculate the mass defect to determine the stability of a nucleus.
    • A larger mass defect indicates a more tightly bound nucleus.
