Not in our Sun, but heavy elements up to and including iron are formed in very massive suns (stars). Elements heavier than iron are formed with suns die in a supernova.
A. Helium and carbon. The other heavier elements such as iron, uranium and lead will be created only in the explosions of supernova stars, such as the one discovered just last week (late May, 2011).
oxides of iron are formed
Elements that are formed in cool stars are heavy but not heavier than iron. (Elements that are heavier than iron are formed in a supernova.)
The iron cores in the centers of some planets didn't come into existence in these planets; the iron was created in the supernova explosions of ancient stars, and blasted into space during the explosions. Our solar system including the Sun and all the planets was formed as gravity caused the gas & dust clouds in space to fall together. We're not sure why the Sun got most of the hydrogen, while the planets were formed from primarily the heavier elements. What we can be sure of is that the core of our Sun isn't nearly hot enough or dense enough to fuse lighter elements into iron, and it's a good thing - because fusing elements heavier than iron would suck energy OUT of the core, and cause the Sun to collapse and then explode in a supernova. That'll never be an issue for us, because the Sun will NEVER be hot and dense enough to do that. It doesn't have enough mass.
It is possible to make iron-bismuth alloy.
iron
It is said that when sun dies from hydrogen to iron elements are formed and when busted spread in space .the other elements are formed by chemical reaction by these elements

Reacting iron with sulfur an iron sulfide is formed, not a mixture.
when nitric acid and iron react together Iron Nitrate is formed and hydrogen gas
After the reaction of iron with an acid a salt is formed, not a hydroxide.
