How many unstable isotophes are in xenon?

The number of unstable isotopes cannot be determined. Xenon has 9 stable or primordial isotopes. These include isotopes whose half-life is greater than 80 million years which is long enough for some of the atoms to have survived. It is also possible that so-called stable isotopes are not really stable but have half-lives of more than 10^22 years.Of the 9 Xenon isotopes,134Xe has a half-life of 1.1*10^16 years;136Xe has a half-life of 8.5*10^21 years;124Xe has a half-life of 1*10^17 years.
