Why is there is so much iron?
$begingroup$
We all know where iron comes from.... but as I am reading up on supernova's it got me wondering why there is as much iron as there is in the universe?
Brown dwarf's do not deposit iron...
White dwarf's do not deposit iron...
Type I supernovas leave no remnant so I can see where there would be iron released.
Type II leave either a neutron star or black hole. As I understand it, the iron ash core collapses and the shock wave blows the rest of the star apart. Therefore no iron is released. (I know some would be made in the explosion along with all of the elements up to uranium. But would that account for all of the iron in the universe?)
Hypernova's will deposit iron... (but they seem to be really rare)
Do Type I supernova happen so frequently that iron is this common? Or am I missing something???

Type II were much more common in the early universe, and those neutron stars released their ash during mergers, and black hole Quasars made sure everything stayed hot.

in absolute terms, there is not a lot of iron in the universe. because of the manner in which our solar system formed, there happens to be a lot of iron concentrated in the earth, but the percentage of iron in the earth is in no way representative of the percentage of iron in the universe.

The nucleosynthesis in the inner of the stars generates energy: The comes huge amounts of energy from generating Helium form hydrogen, the star gets a lot form generating carbon from helium and so an. This finishes with iron. To generate with larger atomic numbers the star needs energy. Most of them are generated in supernovae, where there is a giant excess of energy.
