Nuclear fission can be similar to nuclear fusion for example they both release heat energy. However, in nuclear fusion:
• two nuclei must join together
• Extremely high temperatures are needed.
To develop further: Nuclear fusion is the joining of smaller nuclei to make larger ones. For example; Deuterium and Tritium form to make a bigger and heavier nucleus and Helium releases a lot of energy. Nuclear fusion also happens in stars..

Fission
Fission is another word for splitting. Nuclear fission is the splitting of large nuclei into smaller nuclei. For example: When a uranium-235 or plutonium-239 nucleus is hit by a neutron, the following happens:
• the nucleus splits into two smaller nuclei, which are radioactive
• two or three more
