State two characteristics of nuclear force. Why does the binding energy per nucleon decrease with increase in mass number for heavy nuclei like `" "^(235)U` ?

Text Solution

Verified by Experts

The binding energy per nucleon decreases with increase in mass number for heavy nuclei like `" "_(92)^(235)U`. These nuclei contain a large number of protons which repel one another. As a result of this repulsive force value of B.E. per nucleon decreases with increase in mass number and such heavier nuclides are unstable.
