An atomic explosion is an explosion that occurs as a result of the rapid release of energy from a high-speed nuclear reaction. The driving reaction may be nuclear fission or nuclear fusion or a multi-stage cascading combination of the two, though to date all fusion-based weapons have used a fission device to initiate fusion, and a pure fusion weapon remains a hypothetical device. Nuclear explosions are used in nuclear weapons and nuclear testing.

When a nuclear weapon is detonated, a rapid chain reaction of nuclear fission or fusion occurs. This chain reaction releases a tremendous amount of energy in a very short period of time, which creates an explosion.

Nuclear fission is the process of splitting a heavy nucleus, such as uranium or plutonium, into two smaller nuclei. This process releases a large amount of energy, as well as neutrons. The neutrons released from one fission event can go on to split other nuclei, creating a chain reaction.

Atomic explosions are incredibly powerful and destructive. They can have devastating effects on both people and the environment. It is important to remember that nuclear weapons are not toys. They are weapons of mass destruction that should never be used.
