Pick out the correct statement from the following.
A
Energy released per unit mass of the reactant is less in case of fusion reaction.
B
Packing fraction may be positive or may be negative.
C
is not suitable for a fission reaction.
D
For stable nucleus, the specific binding energy is low.
Text Solution
Verified by ExpertsThe correct answer is:
B
Mass defect per nucleon is called packing fraction. Packing fraction 
, where 
mass of nucleus, 
mass number.
Packing fraction measures the stability of a nucleus. Smaller the value of packing fraction, larger is the stability of nucleus. Packing fraction may be positive, negative or zero.
