Q. Which one of the following is a possible nuclear reaction?
A) $_{5}^{10}B +_{2}^{4}{He}\ \rightarrow \ _{7}^{13}N +_{1}^{1}H$
B) $_{11}^{23}{Na} +_{1}^{1}{H\ }\ \rightarrow \ _{10}^{20}{Ne} +_{2}^{4}{He}$
C) $_{93}^{239}{Np} \rightarrow_{94}^{239}{Pu} + \beta^{-} + \overline{v}$
D) $_{7}^{11}N +_{1}^{1}H \rightarrow \ _{6}^{12}C + \beta^{-} + \overline{v}$
Explanation
(c) In any nuclear reaction mass number and atomic number should remain conserved. Reaction (c) satisfies this condition. Also for$_{93}^{239}{Np}$, neutron to proton ratio is greater than 1.52 which makes it unstable.
