Question 23

Plutonium-239 can undergo nuclear fission in many ways. Which equation correctly shows a possible fission reaction for plutonium-239?

A

01n+94239Pu→54134Xe+40103Zr+301n{}^{1}_{0}\text{n} + {}^{239}_{94}\text{Pu} \rightarrow {}^{134}_{54}\text{Xe} + {}^{103}_{40}\text{Zr} + 3 {}^{1}_{0}\text{n}01​n+94239​Pu→54134​Xe+40103​Zr+301​n

B

01n+94239Pu→54134Xe+40104Zr+301n{}^{1}_{0}\text{n} + {}^{239}_{94}\text{Pu} \rightarrow {}^{134}_{54}\text{Xe} + {}^{104}_{40}\text{Zr} + 3 {}^{1}_{0}\text{n}01​n+94239​Pu→54134​Xe+40104​Zr+301​n

C

01n+94239Pu→54134Xe+41103Nb+301n{}^{1}_{0}\text{n} + {}^{239}_{94}\text{Pu} \rightarrow {}^{134}_{54}\text{Xe} + {}^{103}_{41}\text{Nb} + 3 {}^{1}_{0}\text{n}01​n+94239​Pu→54134​Xe+41103​Nb+301​n

D
