Nuclear bomb

A nuclear bomb is a weapon that releases enormous energy through nuclear reactions.

There are two main types:

• Fission weapons (atomic bombs): energy comes from splitting heavy atomic nuclei such as uranium or plutonium.
• Thermonuclear weapons (hydrogen bombs): use nuclear fusion as well as fission and can be vastly more powerful.

A nuclear detonation can cause a blast wave, extreme heat, fires, ionizing radiation, and radioactive fallout, potentially causing catastrophic casualties and long-term environmental effects.

If you’re studying this topic, I can explain the basic physics, history, effects, or differences between atomic and hydrogen bombs without providing weapon-construction instructions.
