Question
Give one example of nuclear fusion.
Advertisements
Solution
There is a release of energy of 3.3 MeV and the formation of the nucleus of the helium isotope `"_2^3He` when two deuterium nuclei `"_1^2H` fuse. The act of fusing this helium isotope with one deuterium nucleus results in the release of 18.3 MeV of energy, transforming it into a helium nucleus (`"_2^4He`).
