Question 613: Atoms & Nuclei

Question

A nucleus $${}_Z^AX$$ has mass represented by M(A, Z). If Mp and Mn 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
2
= [ZM
p
+ (A $$-$$ Z)M
n
$$-$$ M(A, Z)]c
2

Answer

B.E. = [ZMp + (A $$-$$ Z)Mn $$-$$ M(A, Z)]c2

Answer

B.E. = [ZMp + AMp $$-$$ M(A, Z)]c2

Answer

B.E. = M(A, Z) $$-$$ ZMp $$-$$ (A $$-$$ Z)Mn

Answer

B.E. = [M(A, Z) $$-$$ ZMp $$-$$ (A $$-$$ Z)Mn]c2
