Question
Name the nucleus for which the binding energy per nucleon is maximum.

Answer

The total binding energy of any nucleus depends on the number of nucleons present and the binding energy per nucleon represents the stability of the atom.
Binding energy per nucleon for iron ( Fe )
$\overline{B}=\frac{\Delta E}{A}=\frac{492.8}{56}=8.8 MeV$
which is the maximum.
Therefore this nucleus is the most stable.
