Homework Help: Nuclear Binding Energy/nucleon Question

  1. Nov 6, 2011 #1
    1. The problem statement, all variables and given/known data
    Calculate the binding energy per nucleon (J/nucleon) for
    4 He - 4.0026u
    239-Pu - 239.0522u
    2H 2.0141u
    56-Fe 55.9349u

    Which nuclide is the most stable?

    2. Relevant equations


    3. The attempt at a solution
    If I know how to solve the first, I can solve the rest.

    So, calculating for He
    mass of the measured nucleus is 4.0026u
    calculated mass= 2(p+n)=2(1.00728u+1.00866u)=4.03188u
    delta M=-0.2928u


    The correct answer is -1.13x10^-12 J/nucelon

    I'm not sure where I went wrong. Thanks for helping!
