Highest half life element

A half-life of 0.89 ms was calculated: 294 Og decays into 290 Lv by alpha decay. Since there were only three nuclei, the half-life derived from observed lifetimes has a large uncertainty: 0.89 +1.07 −0.31 ms. 294 118 Og → 290 116 Lv + 4 2 He.

The proton has never been observed to decay and a current estimate of the half-life of a proton is at least 1.67 × 10 34 years. So, for all intents and purposes, hydrogen's half-life can be considered infinite. If on the other hand protons do decay, all nuclides will.
