At the center of every atom is a nucleus. Breaking that nucleus apart—or combining two nuclei together—can release large amounts of energy. Nuclear weapons use that energy to create an explosion. Modern nuclear weapons work by combining chemical explosives, nuclear fission, and nuclear fusion.Sep 29, 2016
What causes atomic bomb explosion?
The fission process becomes self-sustaining as neutrons produced by the splitting of atom strike nearby nuclei and produce more fission. This is known as a chain reaction and is what causes an atomic explosion.
What happens in a nuclear bomb explosion?
A nuclear blast, produced by explosion of a nuclear bomb (sometimes called a nuclear detonation), involves the joining or splitting of atoms (called fusion and fission) to produce an intense pulse or wave of heat, light, air pressure, and radiation.
What explosives are used in nuclear weapons?
Nuclear weapon materials Both plutonium-239 and uranium-235 have been used as nuclear explosives in fission weapons.
Can a nuke explode by itself?
Occasionally the digitization process introduces transcription errors or other problems; we are continuing to work to improve these archived versions. Although no accidental nuclear explosion has ever occurred, nuclear weapons, like conventional shells, bombs and rockets, pose accident hazards.
Can a nuclear bomb destroy a whole country?
The UN Office for Disarmament Affairs agrees that one nuclear bomb “can destroy a whole city, potentially killing millions, and jeopardizing the natural environment and lives of future generations through its long-term catastrophic effects”.
Who created atomic bomb?
J. Robert Oppenheimer J. Robert Oppenheimer (1904-1967) was an American theoretical physicist. During the Manhattan Project, Oppenheimer was director of the Los Alamos Laboratory and responsible for the research and design of an atomic bomb. He is often known as the “father of the atomic bomb."
Who nuked Japan?
the United States On August 6, 1945, the United States becomes the first and only nation to use atomic weaponry during wartime when it drops an atomic bomb on the Japanese city of Hiroshima. Approximately 80,000 people are killed as a direct result of the blast, and another 35,000 are injured.

J. Robert Oppenheimer J. Robert Oppenheimer (1904-1967) was an American theoretical physicist. During the Manhattan Project, Oppenheimer was director of the Los Alamos Laboratory and responsible for the research and design of an atomic bomb. He is often known as the “father of the atomic bomb."
Is Hiroshima still radioactive?
Is there still radiation in Hiroshima and Nagasaki? The radiation in Hiroshima and Nagasaki today is on a par with the extremely low levels of background radiation (natural radioactivity) present anywhere on Earth. It has no effect on human bodies.
