Answer 1

Answer:

The expression for packing fraction is

Packingfraction=

massnumber

isotopicmass−massnumber

×

10

4

When the packing fraction has negative value, the mass number is more than isotopic mass. This means that some mass is converted into binding energy.

This stabilizes the nucleus.

Positive value of packing fraction implies for the unstability of nucleus.

Thus this concept primarily discusses the stability of the nucleus.

Thus, Both S and E are correct but E is not correct explanation of S
