$12$C is stable and relatively tightly bound; this nuclide is the most common form of natural carbon.Mouhcine, Hicham $-$ hmouhcine@csus.edu$-$ Part $($a$)$ Calculate BE$/$A$,$ the binding energy per nucleon, for $12$C in megaelectron volts per nucleon. BE$/$A$(12$C$)=7\mathrm{.}490$ Correct! Part $($b$)$ Calculate BE$/$A for $14$C in megaelectron volts per nucleon.
