Question

Which of the following is a fusion reaction?

• A. ${}_1{H}^2{+}_1{H}^2{\to }_{2}H{e}^4$
• B. ${}_1{H}^2{+}_1{H}^2\to 2_{1}H{e}^2$
• C. ${}_1{H}^1{+}_1{H}^1{\to }_{2}H{e}^4$
• D. ${}_1{H}^1{+}_1{H}^2{\to }_{2}H{e}^4+n$

Answer 1

The correct option is A ${}_1{H}^2{+}_1{H}^2{\to }_{2}H{e}^4$

${}_1{H}^2{+}_1{H}^2{\to }_2{He}^4$ is a fusion reaction because here two smaller nuclei fuse together to form a single stable nuclei.
