Which force is responsible for the decay of the neutron into a proton?
Quick Answer
The weak nuclear force is responsible for neutron beta decay. It changes a neutron into a proton while emitting an electron and an antineutrino.
The Full Story
A free neutron is unstable and typically decays after about 880 seconds, or roughly 15 minutes, through the weak interaction. In this process, one of its down quarks changes into an up quark, turning the neutron into a proton. The emitted particles carry away energy and momentum, preserving physical laws. This decay is fundamental to nuclear physics and to how many radioactive isotopes transform over time.
Key Facts
1.A free neutron’s lifetime is about 880 seconds
2.Beta decay is governed by the weak force
3.The neutron contains one up quark and two down quarks
