Chemistry Question on Nuclear physics
Hydrogen bomb is based on the principle of :
A
artificial radioactivity
B
nuclear fusion
C
natural radioactivity
D
nuclear fission
Answer
nuclear fusion
Explanation
Solution
Hydrogen bombs are based on the principle of uncontrollable nuclear fusion. In Nuclear fusion, the nuclei of two light atoms combine to form a new nucleus.
Thus, the correct answer is B Nuclear Fusion.
Applications of Nuclear Fusion
- No combustion occurs in nuclear power (fission or fusion), so there is no air pollution.
- Fusion reactors will not produce high-level nuclear wastes like their fission counterparts, so disposal will be less of a problem.
- Wastes will not be of weapons-grade nuclear materials as is the case in fission reactors.
Additional Understanding: Difference Between Nuclear Fission and Nuclear Fusion
| Nuclear Fission | Nuclear Fusion |
|---|---|
| Nuclear fission splits a heavy atom into two or smaller ones. | Nuclear fusion combines two or more small atoms to form a large atom. |
| Nuclear Fission doesn't occur naturally. | Every star uses nuclear fusion to produce energy. |
| It produces a large quantity of energy. | It produces greater energy than the fission reaction. |
