The weak force is the one that allows a quark to turn into a different flavor of quark, thus allowing a neutron to transform into a proton, or a proton to transform into a neutron. In the case of the neutron, one of its down quarks change to an up quark, emitting a W- boson in the process. The boson is itself unstable and rapidly decays into an electron and an electron antineutrino. In the case of the proton, one of its up quarks changes into a down quark, and a W- boson appears briefly, then transforms into a positron and an electron neutrino. If any of this sound familiar, it is because this is the mechanism behind beta decay. There are two kinds of beta decay (beta plus and beta minus), and you can review them and related material by using the links below to related questions.
It seems to operate on all fermions -- ie, all particles with spin equal to 1/2
nuclear decay
Fussion and fission
electromagnetic - holds electrons to nucleusweak - mediates neutron decay processstrong - holds nucleus togethergravity - has no effectOnly 3 of the 4 forces act to hold atoms together.
There are two forces responsible for radioactivity: the Strong nuclear force and the Weak nuclear force.
weak force
The force between nucleons is called nuclear force.

The strong nuclear force and the weak nuclear force act within the nucleus to hold it together.
Mostly the strong force and weak force, these act in/on nucleus.
The weak force
They are the shortest range of the four forces, unable to act outside the diameter of the atomic nucleus.

The four fundamental forces of nature are gravity, the electromagnetic force, the strong force (strong nuclear force or strong interaction), and the weak force(weak nuclear force or weak interaction).
