SUMMARY
The binding energy of a neutron in the nitrogen-14 (14N) nucleus is calculated using the mass defect method. The mass of nitrogen is 14.007 amu, while the calculated mass from its constituents (7 protons and 7 neutrons) is 14.115 amu, resulting in a mass defect (Δm) of 0.10839 amu. This mass defect, when converted using the equation E=Δm * 931.5 MeV/amu, yields a total binding energy of approximately 100.96 MeV for the nucleus. Dividing this by 14 gives a binding energy per neutron of 7.21 MeV, which was identified as incorrect due to a potential oversight in unit conversion.
PREREQUISITES
