The binding energy per nucleon is maximum in case of (a) ₂⁴He (b) ₂₆⁵⁶Fe (c) ₅₆¹⁴¹Ba (d) ₉₂²³⁵U

Answer: (b). On the binding energy curve BE/A is maximum (about 8.8 MeV) near A = 56. He-4 ( ≈ 7.1 MeV), Ba-141 and U-235 ( ≈ 7.6 MeV) are all lower. So the answer is (b) ₂₆⁵⁶Fe.

Mass Defect & Binding Energy

The binding energy per nucleon is maximum in case of

Show answer and solution

Answer: (b)

On the binding energy curve $BE/A$ is maximum (about $8.8$ MeV) near $A = 56$ .
He-4 ( $\approx 7.1$ MeV), Ba-141 and U-235 ( $\approx 7.6$ MeV) are all lower.
So the answer is (b) ${}_{26}^{56}\text{Fe}$ .
