An ''H bomb'' is a commonly used name.
hydrogen bomb, or a nuclear bomb
hydrogen bomb, or a nuclear bomb
Another name for heat of fusion is enthalpy of fusion.
A hydrogen bomb is called so because it mainly relies on the fusion of hydrogen isotopes to release energy. The fusion process is what distinguishes it from an atomic bomb, which relies on nuclear fission.
Although the name suggests that the bomb solely uses nuclear fusion to create mass destruction, a Hydrogen bomb actually contains both fission and fusion fuels. Since fusion requires such a high energy input to initiate, a fission bomb is required to detonate the fusion component of the Hydrogen bomb, thereby releasing nuclear waste and radiation.
In general, a fusion bomb (hydrogen bomb) is more powerful than a fission (atomic) bomb. Fusion bombs use an atomic bomb to begin the fusion reaction.
If you are asking which has the maximum danger, a hydrogen bomb is one type of nuclear bomb. In general, nuclear bombs can be fission (called atomic) or fusion (hydrogen) A fusion bomb is larger than an fission bomb, and actually uses a fission bomb to start the fusion reaction.

Nuclear bomb can mean either fission or fusion bomb. Hydrogen bomb means fusion bomb. The fusion bomb can be built with any yield one wants, just by adding more stages with more fuel. The fission bomb has a theoretical maximum yield that cannot be exceeded.
Detonation of a fusion hydrogen bomb is initiated by the primary fission bomb, which generates high temperatures and pressures needed to trigger fusion reactions in the hydrogen isotopes. The fission bomb compresses and heats the fusion fuel to the point where nuclear fusion reactions can occur, releasing vastly more energy than the fission reaction alone.
