Question

What is the half life of neutron?

Answer 1

? doesn't make sense

neutrons by themselves aren't radioactive...a neutron is a subatomic particle

Answer 2

A free neutron (i.e. not bound within the nucleus of an atom) has a half-life of 10-15 minutes. It seems that different sources disagree upon the value - I have seen values as low as 613 seconds and as high as 885 seconds. The latter value (a bit below 15 minutes) is, I think, the currently accepted value; it was given in the 2006 Particle Data Group review of particle physics.

It decays to a proton, an electron, and an electron anti-neutrino. In doing so, the system decreases its total energy by about 780 keV.

Answer 3

half-life of neutron is 10.3 min

decay process is

neutron ---> proton + electron + neutrino

loss mass 0.000 84 amu

equiv energy 0.782 45 MeV

Answer 4

Depends on what it is up to.
