Question

The 2He4 nucleus contains 2 protons and 2 neutrons. The sum of the individual mass of
two protons and two neutrons are 4.0331 a.m.u. However, when the mass of the nucleus
was measured experimentally it was found to be 4.0128 a.m.u. Calculate the mass defect and the binding energy of the nucleus.

Answer 1

Answer:

To calculate the mass defect: add up the masses of each proton and of each neutron that make up the nucleus, subtract the actual mass of the nucleus from the combined mass of the components to obtain the mass defect
