MCQ
The correct equation of nuclear fusion reaction is:
  • A
    ${ }_1 \mathrm{H}^1+{ }_1 \mathrm{H}^1 \rightarrow \mathrm{H}_2$
  • B
    ${ }_1 \mathrm{H}^2+{ }_1 \mathrm{H}^1 \rightarrow{ }_2 \mathrm{He}^4+{ }_0 \mathrm{n}^1$
  • ✓
    ${ }_1 \mathrm{H}^2+{ }_1 \mathrm{H}^2 \rightarrow{ }_2 \mathrm{He}^4+$ energy
  • D
    ${ }_2 \mathrm{H}^2+{ }_3 \mathrm{H}^2 \rightarrow{ }_5 \mathrm{H}^2$
✓

Answer

Correct option: C.
${ }_1 \mathrm{H}^2+{ }_1 \mathrm{H}^2 \rightarrow{ }_2 \mathrm{He}^4+$ energy

In nuclear fusion reactions, the heavy isotopes of Hydrogen take part like deuterium ${ }_1 H^2$ and tritium ${ }_1 H^3$ as they have extra neutron.
