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.

Thanx very much Meir I got the point.

I have difficult on finding the numbers of neutrons or protons can occupy the following energy states: (1g), (g 9/2) and (g 7/2).

Can any one explain to me about parity and spin of nuclei or give me the site.example find the parity and spin of Ca with molar mass 47 or Mn molar mass 50.

Can you tell me how do you came to E^2

Please,can any one give me a good site of packing fraction of an element topic.

I want to calculate the density of plutonium,which has molar mass of 244 and atomic number 94.my problem is the volume can I use the standard volume of gas molecule 22.4?

Please can anybody help on this. Use (beta,delta)definition of a limit to prove that lim (x+y/x^2+y^2+1) = 0 (x,y)-(0,0)
