isotope
A variant of a chemical element whose atoms have the same number of protons but a different number of neutrons in the atomic nucleus. Isotopes of an element usually behave very similarly chemically, but they can differ in their mass and radioactivity.
Kohlenstoff-14 ist ein radioaktives Isotop des Kohlenstoffs.
Carbon-14 is a radioactive isotope of carbon.

'Isotop' (isotope) is used mainly in the technical language of chemistry, physics, and medicine. In everyday life, the word usually appears in scientific, technical, or medical contexts.
Das Isotop wird im Labor mit speziellen Geräten untersucht.
The isotope is examined in the laboratory using special equipment.
Common collocations include 'radioaktives Isotop' (radioactive isotope), 'stabiles Isotop' (stable isotope), and 'Isotop eines Elements' (isotope of an element). These adjectives describe important properties of the isotope.
Für die Untersuchung wurde ein stabiles Isotop des Elements verwendet.
A stable isotope of the element was used for the examination.
In scientific texts, the name of the element is often written together with a number, for example 'Kohlenstoff-14' (carbon-14). The number indicates the total number of protons and neutrons in the isotope's atomic nucleus.
Das Isotop Kohlenstoff-14 wird zur Altersbestimmung archäologischer Funde verwendet.
The isotope carbon-14 is used to determine the age of archaeological finds.
