The average binding energy per nucleon is maximum for the nucleus… - Vidyadip

MCQ

The average binding energy per nucleon is maximum for the nucleus:

A
$_2 \mathrm{H}^4 $
B
$_8 \mathrm{O}^{16} $
✓
$_{26} \mathrm{Fe}^{56}$
D
$_{92} \mathrm{U}^{238}$

✓

Answer

Correct option: C.

$_{26} \mathrm{Fe}^{56}$

Binding energy per nucleon increases with atomic number. The greater the binding energy per nucleon the more stable is the nucleus.
For $_{26} \mathrm{Fe}^{56}$number of nucleons is $56.$
This is most stable nucleus, since maximum energy is needed to pull a nucleon away from it.
