Nuclear bomb
A nuclear bomb is a powerful weapon that uses nuclear reactions to release a massive amount of energy in the form of an explosion. There are two main types of nuclear bombs:
⸻
- Fission Bombs (“Atomic Bombs”)
• These work by splitting heavy atomic nuclei, such as uranium-235 or plutonium-239.
• The process is called nuclear fission, and it releases a huge amount of energy.
• Example: The bombs dropped on Hiroshima and Nagasaki in 1945.
⸻
- Fusion Bombs (“Hydrogen Bombs”)
• These use fission to start a fusion reaction, where light nuclei (like hydrogen isotopes) are forced together to form heavier nuclei.
• This process, called nuclear fusion, releases even more energy than fission.
• Hydrogen bombs are much more powerful than atomic bombs.

Effects of a Nuclear Bomb:
• Blast wave that destroys buildings.
• Extreme heat that can cause fires and burns.
• Radiation that can harm or kill living beings and cause long-term health problems like cancer.
• Fallout, which is radioactive dust that spreads over large areas.

Summary:
A nuclear bomb is one of the most destructive weapons ever created, capable of causing mass destruction in seconds. Its use is governed by strict international laws due to the catastrophic humanitarian and environmental consequences.
