These processes produce most of the chemical elements in the universe heavier than zirconium (element 40), because nuclear fusion processes become increasingly inefficient and unlikely for elements heavier than this. By convention, such heavier elements produced in normal elemental abundance, are not referred to as "nucleogenic".
These processes account for most of the heavy elements in the universe that have atomic numbers higher than zirconium (element 40), because nuclear fusion becomes less effective and improbable for elements with atomic numbers greater than this. Heavier elements produced in typical quantities are not referred to as "nucleogenic" by convention.
