Q. The average binding energy per nucleon is maximum for the nucleus
A) $\ _{2}{He}^{4}$
B) $\ _{8}O^{16}$
C) $\ _{26}{Fe}^{56}$
D) $\ _{92}{He}^{238}$
Explanation
(c) Binding energy per nucleon increases with atomic number. The greater the binding energy per nucleon the more stable is the nucleus
For $\ _{26}{Fe}^{56}$ number of nucleons is 56
This is most stable nucleus, since maximum energy is needed to pull a nucleon away from it
