Web21 apr. 2015 · The half life of U235 is 700 million years, and the half life of U238 is 4500 million years. That explains why U238 is so much more abundant than U235 - it's more stable, due to the extra 3 neutrons in the nucleus. It depends not on the number of neutrons it has but the number of neutrons that it releases in each step of the chain reaction.
