英语百科
Isotopes of palladiumNaturally occurring palladium (Pd) is composed of six stable isotopes, Pd, Pd, Pd, Pd, Pd, and Pd, although two of them are theoretically unstable. The most stable radioisotopes are Pd with a half-life of 6.5 million years, Pd with a half-life of 17 days, and Pd with a half-life of 3.63 days. Twenty-three other radioisotopes have been characterized with atomic weights ranging from 90.949 u (Pd) to 123.937 u (Pd). Most of these have half-lives that are less than a half an hour except Pd (half-life: 8.47 hours), Pd (half-life: 13.7 hours), and Pd (half-life: 21 hours). |
