What is the explosive force of one Hydrogen atom?

Answer 1

One hydrogen atom by itself, although it releases quite a bit of energy for its size, is probably not really all that much. However, when you have a lot of them (such as in the case of the H-bomb) it is a completely different story...) Answer 2. The H-bomb doesn't use hydrogen ( 1H ) as an explosive. The first US thermonuclear device used tritium ( 3H ). It exploded, but was much too heavy to be a weapon. Since then, operational weapons use lithium deuteride ( 6Li 2H ). Normal hydrogen 1H will not explode. It will fuse if subjected to the temperatures and pressures found inside a star; that's how our sun stays hot. The fusion inside the sun is a complex series of reactions, the end result of which is four hydrogen atoms becoming a helium atom 4 1H -> 4He + 26 MeV (and some other bits and pieces). This process has a rather low probability in a star like ours - that is why it has been shining for about 5 billion years and will go on for another 5 billion without the hydrogen ever exploding. So, the energy derived from hydrogen fusion is about 6.5 MeV per atom, but we have no way to use it, peacefully or otherwise.
