Explanation:

An atomic bomb or nuclear bomb is a device that obtains a large amount of explosive energy through nuclear reactions. Its operation is based on provoking a sustained nuclear chain reaction. It is among the so-called weapons of mass destruction and produces a distinctive mushroom-shaped cloud when detonated at low altitude above the surface. One of the first atomic bombs was developed by the United States during the Second World War, thanks to the Manhattan Project, and is the only country that has made use of it in combat (in 1945, against the Japanese cities of Hiroshima and Nagasaki).
