- Increase continuously with mass number
- Decreases continuously with mass number
- Remains constant with mass number
- First increases and then decreases with increase in mass number
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The binding energy per nucleon first increases up to iron-$56$, then decreases gradually as shown in the figure.
As $Z$ increases the number of nucleons in nuclei increase.
Hence the binding energy per nucleon first increases and then decreases with increase of mass number.
As $Z$ increases the number of nucleons in nuclei increase.
Hence the binding energy per nucleon first increases and then decreases with increase of mass number.
