It could be either one depending on the device used in the weapon. Some bombs and missile warheads were the same device and thus had the same yield.
If by "bomb" you mean a conventional explosive weapon, then the nuclear weapon is more powerful.
Nuclear. Napalm is simply gelled gasoline fire bomb.
The terms "atomic bomb" and "nuclear bomb" are general terms and can pretty much be used interchangeably. That said, there isn't any difference between them, and one is not more powerful than the other in that light.
The 'uranium bomb' is an A-bomb and is a first generation nuclear weapon. The hydrogen bomb or H-bomb is a 2nd generation nuclear weapon and generally many times more powerful. 'H-bomb' can also refer to 3rd generation nuclear weapons that have an additional mass off uranium to provide further fuel, triggered by the 2nd generation fusion reaction; these are the most powerful. But recent studies show that the H-Bomb has more mass, therefore more energy, and therefore has more energy. So the H-bomb is more powerful.
Well, there are two types of Nuke, A bomb and a missile or commonly referred to as 'Nuclear Bomb' and 'Nuclear Warhead (or missile)'. It looks like a standard bomb in shape but not size. But there are two versions of Nuclear bomb, Fission and Fusion. The Fission one is more like a standard bomb but larger and the Fusion one looks like a Mini-Missile but is still dropped like a bomb. The Nuclear Warhead (or missile) looks like a missile obviously. The easiest way to answer this question is to look on Google Images and next time you wonder something like this, Please, Don't waste the good people's time to answer your stupidity and minor amount of common sense.
the A-bomb has got more powerful as the advances in nuclear physics has improved.
perhaps biological
No, an atomic bomb uses fission, but a nuclear or thermonuclear bomb combines fission and nuclear fusion. Therefore, a nuke is more powerful than an atom bomb.
nuclear weapons of the fission fusion type, the so called H-Bomb, are the most powerful of all weapons but their ouput can be tailored for specific purposes. Whatever their size they are inevitably more powerful than any conventional explosive.
An atomic bomb has more destructive potential, but a large, long-lived tornado would probably release more energy than a small nuclear weapon.
WW2 ended with the nuclear attack on Japan. The cities of Hiroshima and Nagasaki suffered the consciences of the nuclear bomb. With the United States using these powerful weapons, Russia begun research on the nuclear bomb and in a period of time, they got their nuclear bomb ready. The nations in power were in the "who got the most powerful bomb" race. The nuclear arms race was central to the Cold War. Many feared where the Cold War was going with the belief that the more nuclear weapons you had, the more powerful you were. Both America and Russia massively built up their stockpiles of nuclear weapons. The world greatly changed when USA exploded the H-bomb in 1952. This one bomb was smaller in size than the Hiroshima atomic bomb but 2500 times more powerful. The Russians produced an H-bomb in 1953 and the world became a much more dangerous place.
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.
