Xenon-124 isotope has a longer half life.
- The duration needed for a quantity to decrease to half of its initial value is known as the half-life.
- One of those isotopes whose half life are longer is xenon 124, whose half-life has been calculated by experts to be 18 sextillion years due to its disintegration into tellurium 124.
- Half-life does not imply that atoms degrade at a constant rate. The figure simply represents the time it will take, on average, for the majority of a radioactive element to diminish itself by half.
- While the majority of xenon isotopes have half-lives of less than 12 days, Xenon-124 is believed to have extraordinarily long half-lives and to be fundamentally stable.
- These decays, which are the rarest processes ever directly recorded, have been detected in the XENON1T detector in 2019.
Thus Xenon-124 has highest half life.
