Question

An example of nuclear fusion reaction is -

• A. ${}_{90}{}^{233}\mathrm{Th}+{}_0{}^1\mathrm{n}\to {}_{90}{}^{234}\mathrm{Th}$
• B. ${}_{48}{}^{113}\mathrm{Cd}+{}_0{}^1\mathrm{n}\to {}_{48}{}^{114}\mathrm{Cd}+\mathrm{\gamma }-\mathrm{rays}$
• C. ${}_1{}^3\mathrm{H}+{}_1{}^1\mathrm{H}\to {}_2{}^4\mathrm{He}$
• D. ${}_{92}{}^{239}\mathrm{U}\to {}_{93}{}^{239}\mathrm{Np}+{}_{-1}{}^0\mathrm{e}$

Answer 1

The correct option is C

${}_1{}^3\mathrm{H}+{}_1{}^1\mathrm{H}\to {}_2{}^4\mathrm{He}$

Nuclear fusion is a reaction in which two or more nuclei fuse together to produce different nuclei with different mass numbers and atomic numbers.

When two isotopes of hydrogen atoms fuse together, then helium is formed.

${}_1{}^3\mathrm{H}+{}_1{}^1\mathrm{H}\to {}_2{}^4\mathrm{He}$

So, this process is nuclear fusion.

Final answer:

Option C is the correct answer.
