The half-life of approximately 15 minutes for free neutrons is considered long. It's actually the longest for any sub-atomic particle if I recall correctly.

- batbomb 8y agoI think protons would like to have a word with you.
- _Microft 8y agoProton decay has never been observed, afaik. Edit: that's still the case. Since protons can not decay in the standard model, actually observing it would be huge.
- NZGumboot 8y agoFree protons (protons outside of an atom) have never been observed to decay. Protons inside a nucleus can of course decay, see: https://en.wikipedia.org/wiki/Positron_emission https://en.wikipedia.org/wiki/Positron_emission
