Question

Identify which of the following equations represents a nuclear fusion 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 A ${}_1^{2}H{+}_1^{2}H\to {}_1^{3}H{+}_1^{1}H+$ energy

Nuclear fission is a reaction where a nucleus is broken and forms another nucleus/nuclei. Options B, C, D and E are examples of nuclear fission reactions whereas option A describes the nuclear fusion reaction as two nuclei combine to form a new nucleus.
