Twenty - eight radioisotopes have been characterized with the most stable being Ag with a half - life of 41.29 days, Ag with a half - life of 7.45 days, and Ag with a half - life of 3.13 hours . </P> <P> All of the remaining radioactive isotopes have half - lives that are less than an hour and the majority of these have half - lives that are less than 3 minutes . This element has numerous meta states with the most stable being Ag (t 418 years), Ag (t 249.79 days) and Ag (t 8.28 days). </P>
