- The weak nuclear force was responsible for the creation of elements in the early universe including hydrogen, helium, and lithium. Today it plays a key role in the nuclear fusion reactions that power the sun and other stars.
- The weak nuclear force is responsible for the decay of radioactive isotopes, as well as for other nuclear reactions such as beta decay and neutrino interactions.
- When unstable radioactive isotopes decay, they emit radiation and transform into a more stable elements.
- In beta decay, a neutron in the nucleus of an atom decays into a proton, an electron, and an antineutrino.
- neutrino interactions occur in nuclear reactors. Neutrinos are very light particles that rarely interact with matter, but they can interact with the nuclei of atoms through the weak nuclear force.
- The weak nuclear force is a very weak, but it has a long range. It is also very selective, interacting only with certain types of subatomic particles.
- The weak nuclear force is mediated by a family of particles called W and Z bosons.
