प्रश्न
Give two examples of nuclear fusion.
उत्तर
- \[\ce{\underset{\text{(proton)}}{^1_1H} + \underset{\text{(proton)}}{^1_1H} -> \underset{\text{(deuterium)}}{^2_1H}} + 0.42 \text{ MeV}\]
- \[\ce{\underset{\text{(deuterium)}}{^2_1H} + \underset{\text{(deuterium)}}{^2_1H} -> \underset{\text{(tritium)}}{^3_1He}} + \underset{\text{(proton)}}{^1_1\ce{H}} + 4.0 \text{ MeV}\]
- \[\ce{\underset{Deuterium}{^2_1H}+ \underset{Tritium}{^3_1H} -> \underset{Helium}{^4_2He}+ \underset{Neutron}{^1_0n}+ 17.6 MeV}\]
