"WebWhat are Radioactive elements? Some elements of atomic nuclei are unstable because of the presence of excess nuclear charge inside it, so these nuclei undergo radioactive decay to form stable nuclei. These elements are called radioactive elements. The stability of nuclei of an element can be calculated by n/p (neutron to proton ratio). " - Elements that are stable
