That depends on its design: known fielded bombs have had yields from 0.1 kiloton to 57,000 kilotons. Bombs with lower and higher yield are definitely possible, if someone wanted to make them.
About .02 megatons. It was a twenty kiloton bomb. A mere firecracker compared to today's whizbangs.
Atomic bombs come in a wide variety of sizes. Their explosive power is usually measured in terms of an equivalent number of tons of dynamite. Smaller bombs range in the kilotons (thousands of tons) while larger bombs are in the range of megatons (millions of tons). Even a small atomic bomb is extremely powerful, much more powerful than any conventional bomb. A large atomic bomb can destroy an entire city.
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.
perhaps biological
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.
20 kilotons
A nuclear bomb is extremely powerful, and that's why there are many countries seeking to obtain this power. Since the US is such a "responsible" country, the president is only aloud to look at the directions of how to control our countries nuclear power when in an emergency. The power of a nuclear bomb is typically measured in kilotons or megatons. 1 megaton is the equivalent of 1 million tons of TNT (similar to dynamite) blowing up. The largest nuclear bombs were around 50 megatons, or 50 million tons (or 50 billion kilograms) of TNT. The smallest nuclear bombs were around 10 tons (yes, that is only 0.01 kiloton). Note that at this time (2013) no country stockpiles bombs either that large or that small (about 50 kilotons to 300 kilotons is currently typical). Also, a nuclear bomb is powerful enough to take out an entire city, while spreading deadly radioactive fallout throughout the area. There is still some leftover radiation in places like Hiroshima and the various above ground test sites.
If by "bomb" you mean a conventional explosive weapon, then the nuclear weapon is more powerful.
The Hidrogen Bomb.
Nuclear. Napalm is simply gelled gasoline fire bomb.
The power of a nuclear bomb is a very tiny fraction of the power of the sun.
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.
Yes and no depending on the size of the bomb or reaction and also the size of the state if it was Texas the bomb or reaction would have to be as big as or bigger then an apartment room.But a nuclear bomb isn't the most powerful bomb in the world the most powerful bomb is a hydrogen bomb.
An atomic bomb is a nuclear weapon. A nuclear fusion bomb, (hydrogen, is usually much stronger than a nuclear fission bomb (uranium or plutonium). The weapons detonated in Japan during WWII measured about 15 kilotons equivalent of TNT. Today, most nuclear weapons are measured by megaton (1000X kiloton) equivalents up to a bomb built by the Russians with a possible yield of 100 megatons.
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.
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.
