Understanding Nuclear Reactions
Nuclear reactions involve changes in the nucleus of an atom and can result in the transformation of one element into another. This differs significantly from chemical reactions, which involve the electrons surrounding the nucleus. Some key types of nuclear reactions include:
- Fission: The splitting of a heavy nucleus into lighter nuclei, accompanied by the release of energy.
- Fusion: The combining of light nuclei to form a heavier nucleus, also releasing energy.
- Radioactive decay: The process by which an unstable atomic nucleus loses energy by emitting radiation.
Nuclear reactions can release significant amounts of energy, making them both fascinating and complex. To make this topic more accessible, we provide a nuclear reactions worksheet that includes various problems and scenarios.
