Question

draw the variation of binding energy per nucleon with mass number of atoms and indicate the stable and unstable regions on the diagram​

Answer 1

Answer:

Binding energy per nucleon vs Mass Number

Explanation of Nuclear Fission:

When we move from the heavy nuclei region to the middle region of the plot, we find that there will be a gain in the overall binding energy and hence release of energy. This indicates that energy can be released when a heavy nucleus breaks into two roughly equal fragments. This process is called Nucler Fission.

 

Explanation of Nuclear Fusion:

When we move from lighter nuclei to heavier nuclei, we again find that there will be a gain in  the overall binding energy and hence release of energy. This indicates that energy can be released when two or more lighter nuclei fuse together to form a heavy nucleus. This process is called Nuclear Fusion.
