State what nuclear fusion means.
On Fig. 9.1, sketch how binding energy per nucleon changes with nucleon number $A$ for values of $A$ between $1$ and $250$.
On your line in Fig. 9.1, label a point $X$ that could stand for a nucleus that undergoes alpha-decay.
On your line in Fig. 9.1, label a point $Y$ that could stand for a nucleus that undergoes nuclear fusion.
A nucleus $Z$ undergoes nuclear fission to produce strontium-93 $^{93}_{38}\text{Sr}$ and xenon-139 $^{139}_{54}\text{Xe}$, as shown by $^{1}_{0}\text{n} + Z \rightarrow {}^{93}_{38}\text{Sr} + {}^{139}_{54}\text{Xe} + 2\,^{1}_{0}\text{n}.$ Table 9.1 lists the binding energies of the strontium-93 and xenon-139 nuclei. When $1.00\,\text{mol}$ of $Z$ fissions, $1.77 \times 10^{13}\,\text{J}$ of energy is released. Determine the binding energy per nucleon, in $\text{MeV}$, of $Z$.
