of the 80 elements with a stable isotope, the largest number of stable isotopes observed for any element is ten (for the element tin). no element has nine stable isotopes. xenon is the only element with eight stable isotopes. four elements have seven stable isotopes, eight have six stable isotopes, ten have five stable isotopes, nine have four stable isotopes, five have three stable isotopes, 16 have two stable isotopes (counting as stable), and 26 elements have only a single stable isotope (of these, 19 are so-called mononuclidic elements, having a single primordial stable isotope that dominates and fixes the atomic weight of the natural element to high precision; 3 radioactive mononuclidic elements occur as well). in total, there are 252 nuclides that have not been observed to decay. for the 80 elements that have one or more stable isotopes, the average number of stable isotopes is 252/80 = 3.15 isotopes per element.
