Nuclear fission is a process in which the nucleus of an atom splits into two or more smaller nuclei, releasing a large amount of energy.
Imagine a watermelon splitting into multiple pieces when it's struck by a hammer. The splitting releases a burst of energy, similar to how nuclear fission releases a huge amount of energy when an atom's nucleus splits.
Nuclear Reactor: A device that controls and maintains a sustained nuclear chain reaction for the purpose of producing heat or electricity.
Radioactive Decay: The process in which unstable atomic nuclei emit particles or radiation in order to become more stable.
Chain Reaction: A self-sustaining sequence of reactions where the products from one reaction initiate further reactions.
