There is only one stable [[isotope]] of beryllium, <sup>9</sup>Be. A second isotope, <sup>10</sup>Be, is commonly produced in Earth's atmosphere and accumulates at the surface of the soil. <sup>10</sup>Be currently has a half-life of 1.36 million years and decays through [[proton]] capture to form a [[boron]] isotope. Evolutionists claim that <sup>10</sup>Be abundance can be used to measure the age of geological features through [[radiometric dating]].

==Occurrence in Nature==
Beryllium is very scarce in nature; it has an estimated occurrence of one part per billion (ppb) throughout the universe. It does not occur naturally in a pure form, only in a compound with other elements. Beryllium is a component in many gemstones.
