Whats difference btwn nuclear bomb & atom bomb?

they diffrent,but have the same objective to wipe man from the face of this earth

An atom bomb is an atom bomb. A nuclear bomb is either an atomic bomb or a hydrogen bomb (thermonuclear, bomb). Dan the Answers-Man.

Nuclear- uranium Atomic- hydrogen

Atom bomb uses fission, nuclear bomb uses fussion

They are the same thing, like a car and an automobile are the same thing. Like a doctor and a physician are the same thing. Like a lawyer and an attorney are the same thing.

I think the general nomenclature is that at atom bomb (used in WWII) is a fission bomb and that the modern 'nuclear' bomb is a hydrogen fusion bomb.

Easy to understand. For an example you are Nuclear bomb and your gf is Atom bomb. and both call with different names.

A nuclear weapon is a weapon of enormous destructive potential, deriving its energy from nuclear reactions. Types of weapons Fission bombs derive their power from nuclear fission, where heavy nuclei (uranium or plutonium) split into lighter elements when bombarded by neutrons (produce more neutrons which bombard other nuclei, triggering a chain reaction). These are historically called atom bombs or A-bombs, though this name isn't precise due to the fact that chemical reactions release energy from atomic bonds and fusion is no less atomic than fission. Despite this possible confusion, the term atom bomb has still been generally accepted to refer specifically to nuclear weapons, and most commonly to pure fission devices. Fusion bombs are based on nuclear fusion where light nuclei such as hydrogen and helium combine together into heavier elements and release large amounts of energy. Weapons which have a fusion stage are also referred to as hydrogen bombs or H-bombs because of their primary fuel, or thermonuclear weapons because fusion reactions require extremely high temperatures for a chain reaction to occur. Nuclear weapons are often described as either fission or fusion devices based on the dominant source of the weapon's energy. The distinction between these two types of weapon is blurred by the fact that they are combined in nearly all complex modern weapons: a smaller fission bomb is first used to reach the necessary conditions of high temperature and pressure to allow fusion to occur. On the other hand, a fission device is more efficient when a fusion core first boosts the weapon's energy. Since the distinguishing feature of both fission and fusion weapons is that they release energy from transformations of the atomic nucleus, the best general term for all types of these explosive devices is "nuclear weapon".

I think they're the same thing...just two different names
