Isotopes of rhodium

From Wikipedia, the free encyclopedia

Naturally occurring rhodium (45Rh) is composed of only one stable isotope, 103Rh.[4] The most stable radioisotopes are 101Rh with a half-life of 3.3 years, 102Rh with a half-life of 207 days, and 99Rh with a half-life of 16.1 days. Thirty other radioisotopes have been characterized ranging from 89Rh to 122Rh. Most of these have half-lives that are less than an hour except 100Rh (half-life: 20.8 hours) and 105Rh (half-life: 35.36 hours). There are also numerous meta states with the most stable being 102mRh with a half-life of about 3.7 years and 101mRh with a half-life of 4.34 days.

Quick Facts Main isotopes, Decay ...

The primary decay mode before the only stable isotope, 103Rh, is electron capture and the primary mode after is beta emission. The primary decay product before 103Rh is ruthenium and the primary product after is palladium.
