Question

Which one, among the followings, is a nuclear fusion reaction?

• A. ${}_1{H}^3{+}_1{H}^2{\to }_{2}H{e}^4{+}_0{n}^1$
• B. ${}_{92}{U}^{238}{\to }_{82}P{b}^{206}+8{(}_{2}H{e}^4)+6{(}_{-1}{\beta }^0)$
• C. ${}_7{N}^{12}{\to }_6{C}^{12}+{\beta }^{+}+\gamma$
• D. None of the above

Answer 1

The correct option is A ${}_1{H}^3{+}_1{H}^2{\to }_{2}H{e}^4{+}_0{n}^1$

In a nuclear fusion reaction, two lighter nuclei combine to form a heavier nucleus. Only the first option is showing such reaction.

Hence, $\left(A\right)$ is the correct answer.
