Which Element Has Longest Half-life? The data helped the collaboration make the first definitive measurement of xenon-124’s half-life: 18 billion trillion years. “This is the longest lifetime that we have ever directly measured.” This decay process is called two-neutrino double electron capture. What is the longest half-life of an element? The half-life of xenon-124 —
