How many stable and unstable isotopes of silver are there?

There are many isotopes of silver, but only two are stable. Isotopes of the Element Silver. read more

Naturally occurring silver (47 Ag) is composed of the two stable isotopes 107 Ag and 109 Ag with 107 Ag being the more abundant (51.839% natural abundance). Twenty-eight radioisotopes have been characterized with the most stable being 105 Ag with a half-life of 41.29 days, 111 Ag with a half-life of 7.45 days, and 112 Ag with a half-life of 3.13 hours. read more

c There are unstable isotopes with extremely long half-lives that are also found on Earth, and some of them are even more abundant than all the stable isotopes of a given element (for example, beta-active 187 Re is twice as abundant as stable 185 Re). read more
