What is a nuclear reaction?
Q: What is a nuclear reaction?
A: A nuclear reaction is a process involving an atomic nucleus or more than one nucleus. It can involve nuclear fusion, fission, and radioactive decay.
Q: How does nuclear fusion work?
A: Nuclear fusion occurs when two or more particles collide, resulting in new particles which are different from the first ones.
Q: What is the result of a nuclear fission reaction?
A: In a nuclear fission reaction, the nucleus breaks into pieces.
Q: How does radioactive decay differ from other types of reactions?
A: Radioactive decay is spontaneous and does not need a catalyst like chemical reactions do. Additionally, radioactive decay cannot be stopped, sped up or slowed down.
Q: Where do nuclear reactions occur?
A: Nuclear reactions occur in the sun, in nuclear reactors, in particle accelerators, and in outer space. On Earth they mostly occur only in these special places.
Q: What are some uses for energy released by a nuclear reaction?
A: The energy released by a nuclear reaction can be used to make steam (as in a nuclear power plant) or as energy for bombs.
