Using the data below, determine which one of the three nuclei listed has the greatest mass defect per nucleon. Show the value you obtain for each nucleus.
(i) 612C : atomic mass =12.000000u
(ii) 816O : atomic mass =15.994915u
(iii) 2656Fe : atomic mass =55.934939u
Take mp=1.007276u, mn=1.008665u and me=0.0005486u.
