If M is the mass of a nucleus and A its atomic mass, then the packing fraction is:

A

`(M)/(M-A)`

B

`(M-A)/(A)`

C

`(A)/(M-A)`

D

`(A-M)/(A)`

Text Solution

Verified by Experts

The correct Answer is:
B
Packing fraction determines the stability of nucleus. It is defined as the mass excess per nucleon. Packing fraction =`(M-A)/(A)`
where M is the actual mass of nuclide on atomic mass scale and is mass number
