the difference between a nuclear bomb and a thermonuclear bomb is that :
A nuclear bomb derives it's destructive force from nuclear reaction. That is,fission reaction, fusion reaction or both.
While thermonuclear bomb derives it's own force from a chain reaction in which isotopes of hydrogen combines under extremely high temperature to form helium under a process known as nuclear fusion.
