The term "isotopes" refers to atoms of an element that have the same quantity of protons but differ in the number of neutrons they possess. Isotopes of an element all have the same chemical behavior, but the unstable isotopes undergo spontaneous decay during which they emit radiation and achieve a stable state.
WebTranslations in context of "some isotopes" in English-Italian from Reverso Context: However, it is possible that some isotopes that are now considered stable will be revealed to decay with extremely long half-lives (as with 209 Bi). Translation Context Grammar Check Synonyms Conjugation. The radioactive decay of Pt to Os has a half-life of 6.5(3)×10 years (which is longer than the age of the universe, so it is essentially stable). However, in-situ Os / Os and Os / Os of modern plume related magmas show simultaneous enrichment which implies a source that is supra-chondritic in Pt/Os and Re/Os. Since both parental isotopes have extremely long half-lives, the Os-isotope rich reservoir must be very old to allow enough time for the daughter isotopes to form. These observ…
