(a(i))[2]
Define the term nuclear binding energy.
(a(ii))[2]
Explain what is meant by the term nuclear fission reaction.
(b)[3]
A student suggests that one possible nuclear reaction is $^{56}_{26}\text{Fe} + ^{1}_{0}\text{n} \rightarrow ^{20}_{9}\text{F} + ^{37}_{17}\text{Cl}$. The binding energy per nucleon of a nucleus changes with nucleon number. Use this change to explain why the reaction would not produce a net release of energy.
