What is nuclear fission?
A type of nuclear reaction that is used to release energy from large an unstable nuclei by splitting them into smaller nuclei.
How does nuclear fission work?
Neutron is fired at an unstable nucleus. When the nucleus splits it forms two lighter elements that are roughly the same size. Two or three neutrons are also released when an atom splits, if any of these are slow enough to absorbed by another nucleus then it causes more fission to occur, a chain reaction.
What is nuclear fusion?
Two light nuclei collide at high speeds and fuse to create larger heavier nucleus. The heavier nucleus does not have as much mass as the two separate nuclei did as some mass is converted to energy.
What are the benefits of fusion over fission?
Releases a lot more energy.
