Uranium-236 is created by fusion reactions an unstable isotope of uranium created from four hydrogen atoms used in the h-bomb

Uranium-236 is intermediate nuclei. created by fusion reactions an unstable isotope of uranium created from four hydrogen atoms used in the H-bomb.

Following is the reaction involved in above process:

+  →  →  +  + 3  + 177 MeV

Here, 
= Fission material,
= projectile,
= intermediate nuclei,
and = Fission product

The net force is 100
