Question

How does the binding energy per nucleon vary with the increase in the number of nucleons?(a) Increases continuously with mass number(b) Decreases continuously with mass number(c) First decreases and then increases with increase in mass number(d) First increases and then decreases with increase in mass number

Answer 1

Increases continuously with mass number

Answer 2

Nucleon is the common name which is used for subatomic particles like proton and neutron.

The binding energy of this nucleon is deeply related with the mass number or the nucleon number of thier corresponding nucleus.

We calculate the binding energy by dividing the total nucleus energy with the number of nucleons present in that particular nucleus.

That's why the the intermediate mass number holder nucleons have the largest amount of binding energy.

Similarly, lower or higher mass holder nucleons have the less amount of binding energy due to the mathematical division with the increasing or decreasing nucleon number.

That's why the correct answer of this question is option,D.
