Q94 / 100 · BITSAT 2024 (Memory Based Paper 1) · Physics

The nucleus having highest binding energy per nucleon is

A
${ }_8^{16} \mathrm{O}$
Correct answer
B
${ }_{26}^{56} \mathrm{Fe}$
C
${ }_{84}^{208} \mathrm{~Pb}$
D
$\frac{4}{2} \mathrm{He}$

Solution

The binding energy per nucleon is practically independent of the atomic number for nuclei of mass number in range $30 \lt \mathrm{A} \lt 17^{\circ}$. So, $26^{\mathrm{Fe}^{56}}$ has maximum binding energy per nucleon.

Hence, the correct answer is option: 'B'.
