Explain the following:
(a) Although the nucleus is a part of an atom, the number of electrons present in the atom has no role in deciding the binding energy of the nucleus. Explain.
(b) The atomic mass of 816O is 15.9949amu. Calculate the binding energy per nucleon for this atom. The combined mass of one neutron and one proton is 2.016490amu, and me=0.00055amu.
