Question

Is it accurate to say that neutrons are composed of a proton,an electron and a neutrino; and that in a nucleus, neutronsactually disintegrate (turn into a proton, ejecting an electroninto an orbital) while another electron pops into the nucleus tojoin up with a proton and form another neutron? Thanks!

Explanation / Answer

Outside the nucleus, free neutrons areunstable and have a mean lifetime of885.7±0.8 s (about 15 minutes), decaying by emission ofa negative electron andantineutrino to become aproton.
