SUMMARY
The binding energy of 24 Mg, which consists of 12 protons and 12 neutrons, can be accurately calculated using the equation Eb (MeV) = (ZMp + NMn - Ma)931.494 MeV/u. A common error occurs when the mass defect (delta m) is calculated incorrectly, leading to a negative value. The correct approach includes considering the Coulomb repulsion effect, which can be accounted for using the equation Eb = C1(A) - C2(A^2/3) - C3 Z(Z-1)/A^1/3 - C4(N-Z)^2/A, with constants C1 = 15.7 MeV, C2 = 17.8 MeV, C3 = 0.71 MeV, and C4 = 23.6 MeV. This method provides a positive binding energy, confirming the stability of the nucleus.
