- Involves splitting a heavy nucleus into smaller nuclei, releasing a large amount of energy in the process.

- Typically occurs when a neutron is absorbed by a heavy nucleus, causing it to split into two or more smaller nuclei and release neutrons and energy.

- The energy released in nuclear fission reactions is used to generate electricity in nuclear power plants and can also be used to create nuclear weapons.

Nuclear Fusion

- Involves combining two or more light nuclei into a heavier nucleus, releasing a significant amount of energy in the process.

- Primarily occurs when two nuclei are forced together at high temperatures and pressures, causing them to fuse and release tremendous amounts of energy.

- Nuclear fusion is the process that powers the sun and other stars and is considered a promising source of clean energy, as it has the potential to produce large amounts of energy with reduced radioactive waste.
