Question 568: Atoms & Nuclei

Question

A nucleus $${}_Z^AX$$ has mass represented by M(A, Z). If M
p
and M
n
denote the mass of proton and neutron respectively and B.E. the binding energy in MeV, then

Accepted Answer

The difference in mass of a nucleus and its
constituents, $$\Delta $$M, is called the mass defect and
is given by
$$\Delta $$M = [ZM
p
+ (A $$-$$ Z)M
n
] - M(A, Z)
binding energy = $$\Delta $$Mc
