Please answer this question. Draw a graph showing the variation of binding energy per nucleon as a function of mass number A. The binding energy per nucleon for heavy nuclei (A > 170) decreases with the increase in mass number. Explain.

Biding energy per nucleon decreases after mass number A > 170 because for the elements A > 170 ,
 
number of neutrons in the nuclei is greater than number of protons .
 
For example , Tungsten (W) ,
 
Mass number A = 184 ,Atomic number Z = 74 , Hence Tungsten (W) element has 74 protons and 110 neutrons
 
For example , Gold (Au)
 
Mass number A = 197, atomic number z = 79 . Hence Gold (Au) has 79 protons and  118 neutrons.
 
Greater number of neutrons than protons makes less binding energy to the nucleus .
 
Hence as neutron number inreases , binding energy per nucleon decreases.
