Neutron
Neutrons are the particles on an atom that have a neutral charge. They aren't positive like protons. They aren't negative like electrons. But don't start thinking that they... More »

Neutron - Wikipedia, the free encyclopedia
The neutron is a subatomic particle with no net electric charge and a mass slightly larger than that of a proton. Neutrons are usually found in atomic nuclei. The nuclei of most atoms consist of pro...

A free neutron will decay with a half-life of about 10.3 minutes but it is stable if combined into a nucleus. The decay of the neutron involves the weak interaction as indicated in the Feynman diagram to the right.
