Required Energy

[kidia]

Hi can any body help me on this I really need it.

 

The nuclide Sn has a filled proton shell, 50 being on one of the magic nucleon number. Sb has an extra proton outside this shell to make 51. According to the shell model, extra proton should be easier to remove than a proton from the filled shell. Verify this by calculating the required energy in each case.

Sn mass 121 Atomic Mass (u) 119.902199

Sb mass 120 Atomic Mass (u) 120.903821

 

Mass of hydrogen atom is 1.007825u.

Calculate the energy it takes to remove a proton. If you have a nucleus with Z protons and A total nucleons, compare its mass with the combined mass of a proton (H-1) and a Z-1, A-1 nucleus. The mass difference is proportional to the energy needed to remove the proton (or the energy that would be released if you added the proton)
