Nuclear binding energy is equivalent to

Assertion : The binding energy per nucleon,for nuclei with atomic mass number $A > 100$,decreases with $A$.
Reason : The nuclear forces are weak for heavier nuclei.

Nuclear fission is possible because the binding energy per nucleon ...

The binding energy of a nucleus is equivalent to

If $E_e$ is the energy required to remove an electron from an atom and $E_n$ is the energy required to remove a nucleon from a nucleus,then:

What is the fundamental reason for the chemical energy produced in a chemical process?
