31. Thorium-232 is the lightest primordial nuclide that has left evidence of undergoing spontaneous fission in its minerals. 32. It is also the rarest primordial nuclide in the Universe observed for any element that has any stable isotopes. 33. For a LL nuclide , the integral term vanishes, and the release depends only on the attained countrate. 34. Nickel-62 has the highest nuclear binding energy of any nuclide , at 8.7946 MeV / nucleon. 35. These models can successfully explain nuclide properties, for example, whether or not a certain nuclide undergoes radioactive decay. 36. These models can successfully explain nuclide properties, for example, whether or not a certain nuclide undergoes radioactive decay. 37. Also, articles that aren't elements usually get lower importance, like a notable nuclide uranium-235. 38. Iron is especially common because it represents the minimum energy nuclide that can be made by fusion of helium in supernovae. 39. It is not found on Earth, but its ultimate decay product is its granddaughter, the stable nuclide 60 Ni. 40. In this definition, " stable " means a nuclide that has never been observed to decay against the natural background.
