カルシウムの同位体
1. Isotopes of calciumCalcium (Ca) has a total of 24 isotopes, from Ca to Ca. There are five observationally stable isotopes (Ca, Ca through Ca and Ca), plus one isotope with such a long half-life that for all practical purposes it can be considered stable. The most abundant isotope Ca, as well as the rare Ca, are theoretically unstable on energetic grounds, but their decay has not been observed. Calcium also has a cosmogenic isotope, radioactive Ca, which has a half-life of 102,000 years.
