Actually there are many types. There are also many ways to have two types of nuclear bomb...
Fission bomb: Gun & Implosion; these are the only known practical rapid assembly methods.
Bomb fuel: fission & fusion; only very heavy or very light elements have enough excess nuclear binding energy to drive the reactions.
etc.
there were two types of nuclear bombs. A "gun type" bomb and an implosion type one with a plutonium core
fission and the fusion types
Atomic bombs are a type of Nuclear bomb and there are 2 types of nuclear bombs. The second type of nuclear bomb is a hydrogen bomb.
A nuclear accident is the unintended release of nuclear radiation into the environment, such as damage to a nuclear reactor or to a nuclear weapon (plane crash carrying nuclear bombs, etc). The two basic forms of nuclear weapons are fission and fusion weapons.

Nuclear bombs is all types of bombs that use nuclear energy. It is not a type of bomb,just a category of bombs. hydrogen bomb is the strongest bomb ever, and its blast yield can go up to 100megatons of TNT.
Some bombs are nuclear. But most bombs are not nuclear.
Chemical energy- to begin the explosion- and nuclear energy- the main explosion.
Basically, nuclear energy is used in two ways: * In nuclear reactors, to generate electricity. * In nuclear bombs (atom bombs) to cause destruction on a large scale.
Only two cities in Japan have been attacked with nuclear bombs at the end of WW2: Hiroshima and Nagasaki.
