Normally, when the atom of a radioactive particle decays
, a neutron breaks down into a proton, an electron, and an antineutrino (or a neutrino).
If these particles exist, they will appear as virtual particles in quantum loops, where they can affect the rate and angular distributions of particle decays

A beryllium-7 nucleus decays
into a lithium-7 atom by absorbing an electron, which converts a proton into a neutron.
A radioactive element is an element with an unstable nucleus that decays
