Draw the graph showing thervariation of binding energy per nucleon with mass number. Give therason for the decrease of binding energy per nucleon for nuclei with high mass numbers.

The binding energy per nucleon for nuclei with high mass number is low due to the large coulomb repulsion between the protons inside these nuclei.

Explanation

The graph showing the variation of binding energy per nucleon with mass number is shown below.

The binding energy per nucleon for nuclei with high mass number is low due to the large coulomb repulsion between the proton inside these nuclei.
