MCQ
Hydrogen bomb is based on:
- AControlled chain reaction
- BUncontrolled chain reaction
- ✓Nuclear fusion
- DNuclear fission
✓
Answer
Correct option: C.
Nuclear fusion
Hydrogen bomb is based on nuclear fusion. A large amount of nuclear energy is released by fusion of two light elements $($elements with low atomic numbers$).$
In a hydrogen bomb, two isotopes of hydrogen, deuterium $(1$ proton, $1$ neutron$)$ and tritium $(1$ proton, $2$ neutron$)$ are fused to form a nucleus of helium and a neutron.
This fusion releases $17.6\ MeV$ of energy. Also, there is no limit on the amount of the fusion that can occur.
