Question

When the number of nucleons in a nucleus increases the binding energy per nucleon-

• A. Remains constant with increase in mass number
• B. Increase continuously with increase in mass number
• C. Decrease continuously with increase in mass number
• D. First increases and then decreases with increase in mass number.

Answer 1

The correct option is D First increases and then decreases with increase in mass number.


From, $\text{Binding energy per nucleon vs mass number curve},$ the binding energy per nucleon first increases and then decreases with increase in mass number.
