{{navi|Atombau|Radioaktivität}}'''Isotope''' (griech. ''isos'' = gleich; ''topos'' = der Ort) sind alle Atomarten (= [[Nuklide]]) eines [[PSE|Elementes]], die sich durch die Anzahl der Neutronen im Kern unterscheiden. Hierdurch ergeben sich bei identischen [[Ordnungszahl]]en unterschiedliche Massenzahlen.
Zur Unterscheidung werden Isotope entsprechend dieser Massenzahl benannt, z. B. für
das Element [[Kohlenstoff]] „C-12“ (sprich: "C-zwölf") oder „C-14“. Die alternative Schreibweise dieser Isotope lautet: <sup>12</sup>C bzw. <sup>14</sup>C usw.
{{cb|8|16|17}}
Üblicherweise werden stabile und instabile (= [[radioaktiv]]e) Isotope unterschieden. [[Radioaktiv]]e Isotope zerfallen mit einer charakteristischen [[Halbwertszeit]].
