The binding energies of deuteron \[(_{1}^{2}H)\] and \[\alpha \]-particle \[(\frac{4}{2}He)\] are 1.25 and 7.2 \[MeV\]/nucleon. Which nucleus is more stable?         

Answer:

                The \[\alpha \]-particle (\[\frac{4}{2}\]He) is more stable because of its higher B.E. per nucleon than that of deuteron \[(\frac{2}{1}H)\].
