Question

Which one of the following is a possible nuclear reaction?

• A. ${}_5^{10}B{+}_2^{4}He{\to }_7^{13}N{+}_1^{1}H$
• B. ${}_{11}^{23}Na{+}_1^{1}H{\to }_{10}^{20}Ne{+}_2^{4}He$
• C. ${}_{11}^{239}Np{\to }_{94}^{239}Pu+{\beta }^{-}+\overline{v}$
• D. ${}_7^{11}N{+}_1^{1}H{\to }_6^{12}C+{\beta }^{-}+v$

Answer 1

The correct option is B ${}_{11}^{23}Na{+}_1^{1}H{\to }_{10}^{20}Ne{+}_2^{4}He$

Only in reaction (B), the no of protons, neutrons & electrons are equal on the left and right of the reaction. So, only (B) is a possible nuclear reaction.
