==Key Stage 4==
===Meaning===
'''Unstable Isotopes''' are [[isotope]]s which [[Radioactive Decay|radioactively decay]] to form new [[Stable Isotope|stable isotopes]] of the same [[element]] or a different [[element]].
===About Unstable Isotopes===
: An [[isotope]] may be '''unstable''' if it has too many, too few [[neutron]]s or the [[Atomic Nucleus|nucleus]] is too [[massive]].
: An '''unstable [[isotope]]''' may [[Radioactive Decay|decay]] causing it to transmute into a new [[element]] or a more [[Stable Isotope|stable isotope]] of the same [[element]] by releasing a [[particle]] from the [[Atomic Nucleus|nucleus]].
: An '''unstable [[isotope]]''' may be too [[massive]] so it can lose an [[Alpha Particle|alpha particle]] to become a less [[massive]] [[element]] or it can split into two smaller, more [[Stable Isotope|stable]] [[element]]s in a process called [[Nuclear Fission|nuclear fission]].
