Define Binding Energy?

Obtain the binding energy (in MeV. Of a nitrogen nucleus (._(7)^(14)N) , given m (._(7)^(14)N) = 14.00307 u .

What is the difference between binding energy and disintegration energy so that have the same magnitude?

Define ionization energy.Explain on which the ionization energy depends on .

Why is the binding energy curve steep for light nuclei and falling off slowly for the heavy nuclei?
