For a nucleus `"^AX_Z` having mass number `A` and atomic number Z .
`A`. The surface energy per nucleon `(b_(s))=-a_(1)A^(2/3)`
B.The coulomb contribution to the binding energy `b_(c)=-a_(2)(Z(Z-1))/A^(4/3)`
C. The volume energy `b_(y)=a_(3)A`
D. Decrease in the binding energy is proportional to surface area .
E. While esmating the surface energy,it is assumed that each nucleon interacts with 12 nucleons. `(a_(1),a_(2) and a_(3)` are constants)
