Naturally occurring [[rhodium]] (₄₅Rh) is composed of only one stable [[isotope]], ¹⁰³Rh.<ref>{{cite journal |author=John W. Arblaster |title=The Discoverers of the Rhodium Isotopes.

Thirty other radioisotopes have been characterized with [[atomic weight]]s ranging from {{val|88.949|ul=Da}} (⁸⁹Rh) to {{val|121.943|u=Da}} (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 state]]s with the most stable being ^102mRh (0.141&nbsp;MeV) with a half-life of about 3.7 years and ^101mRh (0.157&nbsp;MeV) with a half-life of 4.34 days.

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]].
