Question

Identify the nuclear fission reaction .

• A. ${}_1^{2}H{+}_1^{2}H{\to }_1^{3}H{+}_1^{1}H+$ energy
• B. ${}_{88}^{226}Ra{\to }_{86}^{222}Rn{+}_2^{4}He$
• C. ${}_{83}^{209}Bi{\to }_{84}^{209}Po{+}_{-1}^{0}e$
• D. ${}_{92}^{235}U{+}_0^{1}n{\to }_{54}^{140}Xe{+}_{38}^{94}Sr{+}_2^{1}n$
• E. ${}_2^{4}He{+}_{13}^{27}Al{\to }_{15}^{30}P{+}_0^{1}n$

Answer 1

The correct option is D ${}_{92}^{235}U{+}_0^{1}n{\to }_{54}^{140}Xe{+}_{38}^{94}Sr{+}_2^{1}n$

${}_{92}^{235}U$+ ${}_0^{1}n$ $\to$ ${}_{54}^{140}Xe$+${}_{38}^{94}Sr$+${}_2^{1}n$

Nuclear fission is a nuclear reaction in which the nucleus of an atom splits into small parts. The fission process often produces free neutrons and protons and releases a large amount of energy.
