Determine the binding energy of an F-19 nucleus.The F-19 nucleus has a mass of 18.99840325 amu.A proton has a mass of 1.00728 amu,a neutron has a mass of 1.008665 amu,and 1 amu is equivalent to 931 MeV of energy.

Question

Quizplus · Accepted Answer

The binding energy is calculated by finding the mass defect and converting it to energy. The mass defect is the difference between the sum of the masses of the protons and neutrons and the actual mass of the nucleus. For F-19, the mass defect is (9*1.00728 + 10*1.008665 - 18.99840325) amu = 0.1565 amu. Converting this to energy gives 0.1565 amu * 931 MeV/amu = 145.6 MeV, which is closest to 143 MeV.
