Atomic+Bomb+WW2

**The Atomic Bomb**
On August 2, 1939, right before World War II started, a race to make the world's first atomic bomb had begun. This idea of an atomic bomb came from Germany. They started trying to harness energy from splitting an atom. In 1940, this information had leaked into Britain. A German refugee, who fled to there, told them that using approximately five kilograms of uranium-235 would make the reaction fast enough that was required for an atomic explosion. This information was sent straight to America. An atomic bomb works by splitting an atom. When an atom splits, its nucleus splits into smaller parts. This causes a nuclear reaction and creates a fission. Then, when the fission is created, a great amount of energy is released. That energy, then, causes a huge explosion. American is where the first atomic bomb was produced. By the time America had made an atomic bomb, the Germans were not even close to creating such a device. Soon after it was created, it was scheduled to be dropped on Hiroshima and Nagasaki. These two places were the first and only cities to ever experience an atomic bomb.
