According to a study from the University of Wollongong, in Australia: Most likely there are roughly 70,000 nuclear bombs in the world. The exact number is unknown, due to military secrecy. The US has the most (or atleast the most documented)- estimates project that the US has 33,000 and the former USSR has around 16,000. Both nations continue to keep many in storage. Great Britain, France, China, India, Pakistan, and Israel among many other nations are known to possess these bombs. Under the Constitution of Japan the country has voluntarily banned itself from ever owning such a destructive weapon.
I doubt if it's possible to answer this question unless you have access to classified information. There have been only two military explosions -- those on Hiroshima and Nagasaki that brought WW2 to an end -- but there was at least one before that, and many since then. The US tested several and, as each country acquired nuclear weapons, and updated those weapons, they wanted to test them. Britain did theirs in Australia, the USSR mostly did their testing underground, as did South Africa, France did theirs in the south Pacific (the US did some there too), and China, Israel, India and Pakistan (have I missed out anyone?) in the places they thought most appropriate. Often the only external signs that bombs had been exploded were the seismographic recordings kept by the countries that were watching for such signs, so probably no one knows, and it would now take a very great and expensive effort by many researchers, with access to the records of the countries concerned, to comb through the evidence of sixty years of nuclear testing to come anywhere near an exact figure.
Improved Answer:
From my estimation as information provided by other literatures, the figure from 1945 - 1998 is estimated to be 2053. This number may be disputed as many test results are questionable. The 7 tested countries included in the figure are (ranked from test dates): U.S. (1032), Soviet Union (715 as of 1990), U.K.(45), France (210), China (45), India (4), Pakistan (2).
North Korea and Israel have both had unconfirmed nuclear tests since then.
This number is a minimum figure as fall-out detections were not made as accurate at the beginning of nuclear era. U.S, Soviet Union, U.K., and France detonated atomic weapons at oversea regions.
There were two atomic bombs dropped on Japan at the end of World War II: Little Boy (Hiroshima) and Fat Man (Nagasaki).
Two, both used against Imperial Japan in 1945.
its over nine thousand
2053
The bombs that were dropped on Hiroshima and Nagasaki were atomic bombs and not nuclear bombs and were designed to explode above the ground and not on impact.
The first atomic bomb was launched in 1945, by the US. It incinerated Hiroshima and Nagasaki, Japan during WWII The above is half true. That was the first time an atomic bomb was used in war, but the first atomic bomb was detonated at the the Trinity Site in White Sands Missile Range, on July 16, 1945.
Most of the bombs (and the V-1 and V-2 missiles) exploded above ground in London, which is why people took shelter in the subways and in basements. Unfortunately, some bombs were made heavy enough to penetrate the ground before exploding. Other bombs destroyed buildings which then collapsed into the subterranean shelters.
In very rough figures the B-29s were flying at about 30000 feet of altitude when they dropped the bombs and the bombs exploded at about 1500 feet of altitude. You can estimate from there.
The two bombs dropped on Japan were released at a little higher than 30,000 feet and exploded at about 1500 feet. You can calculate from there. Bombs dropped for test purposes have been released and exploded at different altitudes.
that depends on the yield of the bombs and how well they are coupled to the ground. one bomb of sufficient yield exploded deep underground inside bedrock will do it.

The first two atomic bombs were set of in the atmosphere, they did not make a hole. Later during the cold war, regulations prevented atmospheric/surface testing and the bombs were set off in deep holes that were pre-drilled in the ground. These holes were as deep as the engineers made them.

The very first atomic bomb was exploded in a test in the New Mexico desert on July 16, 1945. If you'd like to look up more information about it, you can look up the codename "Trinity".
The atomic bomb was a bomb of mass destruction. The bomb was dropped on Japan twice before surrendering after a threat of another attack. The two bombs had the names of little boy and fat man. When the bombs exploded they demolished the buildings and vaporized the people also throwing radiation into the air making it uninhabitable where the bombs exploded. The bombs were dropped from the plane named Enola Gay the name of the pilot's mother.
America exploded a lot of atomic bombs the ones they dropped on Japan were to win the war and to see what would happen if they were dropped on real live people.
Some atomic bombs explode on impact, most explode in the air for maximum destruction caused by the explosion spreading out over a wider area.
The planes carried bombs that exploded when the pilot crashed into targets.
