Atomic Explosion Link

An atomic (fission) explosion occurs when the nuclei of heavy, unstable atoms—typically or Plutonium-239 —are split into smaller parts. This process, known as nuclear fission , releases a massive amount of energy due to the "nuclear difference," where nuclear reactions release roughly a million times more energy than chemical reactions.

When a nuclear weapon detonates, its energy is released in several distinct forms: When a nuclear weapon detonates, its energy is

The following overview summarizes the scientific principles, historical context, and immediate physical effects of an atomic explosion.

To trigger this explosion, the fissile material must reach a , where a self-sustaining chain reaction occurs. In modern designs, this is often achieved through:

: Using conventional high-explosive "lenses" to compress a plutonium core, increasing its density until it becomes supercritical (used in the "Fat Man" bomb and the Trinity test). Physical Effects of the Detonation
