The difference in mass between a nucleus and its constituent nucleons is known as the mass defect, denoted by Δm.
The formula for calculating the mass defect (Δm) is given by :
Δm = Zmp + (A-Z)mn - M
where:
Z is the atomic number of the nucleus,
A is the mass number of the nucleus,
mp is the mass of a proton,
mn is the mass of a neutron,
and M is the actual mass of the nucleus.
The above formula represents the difference between the mass of the individual protons and neutrons that make up the nucleus and the actual mass of the nucleus itself. The mass defect is a measure of the binding energy that holds the nucleus together.
The correct answer is option (2).
