The Manhattan project scientists headed by Robert Oppenheimer.
the atomic bomb that was dropped on hiroshima and nagasaki made an end to World War II and set a deterent to the enemies of the united states ;hey
The 'Fat Man' bomb which was dropped onto Hiroshima was made up of Plutonium. The 'Little Boy' bomb which was dropped onto Nagasaki was made up of Uranium 235.
They dropped in the city call Hiroshima and Nagasaki. The bomb for Hiroshima was the big and killed more people than Nagasaki's atomic bomb. I am sure that to dropping atomic bombs in Japan was mistake, even if they wanted to finish the war quickly. America said that to dropping the bomb in japan saved American solders life. But it also made Japanese people killed a lot. and we shouldn't use it forever and ever and never!
Uranium 235
If you are referring to "the" bombs, it sounds like you're referring to the two "Atomic" bombs that were dropped on the city of Hiroshima on 06 August 1945, and Nagasaki on 09 August 1945, thus ending WWII. If your referring to the Battle of Iwo Jima (where the US flag was raised), bombs and naval guns pounded that whole island.
President Harry Truman gave the order for atomic bombs to be dropped on Hiroshima and Nagasaki.
Atom or atomic bomb is an older term. The modern term is Nuclear Weapon or Nuclear Device. Then of course there are Thermonuclear weapons (typically these are the large strategic nukes), which are also called "Hydrogen Bombs". These typically consist of a primary or trigger, which is basically a small nuclear weapon. This tiny nuke sets off a larger secondary inside the weapon which causes a fusion reaction and a very large explosion.
The American President, Harry Truman, made the decision to drop atomic bombs on the cities of Hiroshima and Nagasaki.
Nuclear bombs made from Plutonium and Uranium.
In the test bomb, the material was plutonium. Plutonium was also used in one of the bombs dropped on Japan, Fat Man. Little Boy, the bomb dropped on Nagasaki, was made of uranium.
Yes the atomic bomb was already made, it was made in the Manhattan Project and secret code so other nation would not know of it, It was later dropped in a desert in New Mexico to test its deadlinest, and then later dropped on Japan TWICE.
it was not discovered it was made it was made in U.S and the Enola Gay dropped the bomb on hiroshema. I think
