The binding energy per nucleon for ${}_1^2H$ and ${}_2^4He$ are $1.1 \; MeV$ and $7.1 \; MeV$ respectively. The energy released in $MeV$ when two ${}_1^2H$ nuclei fuse to form one ${}_2^4He$ nucleus is:

In the process of a nuclear explosion,in which form is the maximum energy released?

In a nuclear reactor,boron rods are used as ...... .

In the proton-proton cycle in the Sun,the energy released when an electron and its antiparticle combine is $\qquad$ .

What is nuclear fusion? Explain giving its nuclear equations and write down the definition of thermonuclear fusion.

Suppose we think of the fission of a $^{56}_{26} Fe$ nucleus into two equal fragments,$^{28}_{13} Al$. Is the fission energetically possible? Argue by working out the $Q$-value of the process.
Given: $m(^{56}_{26} Fe) = 55.93494 \; u$ and $m(^{28}_{13} Al) = 27.98191 \; u$.
