What is the binding energy of an alpha particle?

Question

Quizplus · Accepted Answer

The binding energy of an alpha particle is the energy required to completely separate its constituent nucleons. The mass of an alpha particle is less than the sum of the masses of its constituent nucleons (two protons and two neutrons) due to the strong nuclear force that binds them together. The mass defect of an alpha particle is 0.3727 u, which corresponds to an energy of 28.29 MeV according to Einstein's famous equation E=mc^2. Therefore, the correct choice is (C) 28.29 MeV.
