Weak Nuclear Force

The weak nuclear force is one of the four fundamental forces of nature, responsible for processes like radioactive decay and fusion in stars. Unlike the strong nuclear force, which holds atomic nuclei together, the weak force governs the interactions that change one type of subatomic particle into another. For example, it allows a neutron to turn into a proton, emitting a particle called a neutrino. This force is crucial for the stability of atoms and plays a vital role in the energy production in the sun. It operates at very short distances, much less than the size of an atom.
