What is nuclear fission?

• Nuclear fission is the process of combining the nucleus of an atom into two or more larger nuclei, with the release of a large amount of energy.

• Nuclear fission is the process of converting matter into energy.

• Nuclear fission is the process of releasing energy from the nucleus of an atom without splitting it.
