Define mass defect and state an expression for it.

1.	Define mass defect and state an expression for it.
Answer» The difference between the sum of the masses of all the individual nucleons in a nucleus and the mass of the nucleus is known as the mass defect. Mass defect, ∆m = (Zm_p+ Nm_n) – M where mp is the proton mass, mn is the neutron mass, M is the mass of the nucleus, Z is the atomic number and N = A – Z is the neutron number.

Answer»

The difference between the sum of the masses of all the individual nucleons in a nucleus and the mass of the nucleus is known as the mass defect.

Mass defect, ∆m = (Zm_p+ Nm_n) – M where mp is the proton mass, mn is the neutron mass, M is the mass of the nucleus, Z is the atomic number and N = A – Z is the neutron number.
