The mass of ¹H is 1.007825 u and the mass of ¹n is 1.008665 u. The mass of ¹²C is 12.000000 u, of ¹³N is 13.005739 u, and of ¹⁴N is 14.003074 u. What is the binding energy of the last neutron in ¹⁴N?

Question

Quizplus · Accepted Answer

The binding energy of the last neutron in ¹⁴N is the difference between the mass of ¹³N and the mass of ¹⁴N minus the mass of a neutron. This is:13.005739 u + 1.008665 u - 14.003074 u = 0.011329 uConverting this to MeV using the conversion factor 1 u = 931.5 MeV/c^2, we get:0.011329 u * 931.5 MeV/c^2 = 10.6 MeVTherefore, the binding energy of the last neutron in ¹⁴N is 10.6 MeV.
