==Key Stage 4==
===Meaning==
'''Nuclear fission''' is a process in which a large [[Unstable Isotope|unstable]] [[Atomic Nucleus|nucleus]] splits into two more [[Stable Isotope|stable]] [[Atomic Nucleus|nuclei]].
===About Nuclear Fission===
: '''Nuclear fission''' occurs when a [[massive]] [[Atomic Nucleus|nucleus]] is so [[Unstable Isotope|unstable]] that it splits in two.
: During '''nuclear fission''' [[neutron]]s are also [[emit]]ted.
: '''Nuclear fission''' [[Energy Transfer|transfers]] [[energy]] from the [[Nuclear Potential Energy Store|nuclear potential energy store]] into the [[Thermal Energy Store|thermal energy store]] of the [[material]] and the surroundings.
: '''Nuclear fission''' can be induced in a [[material]] by bombarding [[massive]] [[Atomic Nucleus|nuclei]] with [[neutron]]s. If a [[neutron]] is captured by the [[Atomic Nucleus|nucleus]] it becomes so unstable that it splits in two.
: The [[neutron]]s used to induce '''fission''' must have a low [[energy]] to be captured by a [[Atomic Nucleus|nucleus]] otherwise the [[neutron]]s will just pass straight through without being captured. [[Neutron]]s with the right amount of [[energy]] to be captured are called [[Thermal Neutron|thermal neutron]]s because they have a similar [[energy]] to [[molecule]]s in the [[air]] at [[Room Temperature|room temperature]].
