When it comes to the elements in the periodic table found throughout the Universe, it’s only the first two that originated from the Big Bang: hydrogen and helium. Everything else was formed from stars, whether:
fused in their cores, from lighter elements into heavier ones,
built in supernovae, where the tremendous energy-and-particle release created elements as far up the periodic table as we know how to go,
created from mergers of collapsed objects, like two neutrons stars, which gives rise to the heaviest of elements,
or created afterwards from the nebulous remnants of stars, either by radioactive decay or by those atoms being blasted apart by high-energy cosmic radiation.
