alloys with special properties
Ore
for making elements from helium to nickel and iron, thermonuclear fusionfor making elements past nickel and iron a supernova explosion is needed to force nuclei to fuse more, this destroys the star
iron and sulfur Pyrite is iron sulfide, FeS2.
Iron and oxygen
The two elements that make up steel are iron and carbon. Other elements can also appear in the steel, but these two are the ones that cause it to be called steel.
DYUUNII
Iron is an element in its own right. So there are no two elements that make iron. However, Steel is an alloy of iron and carbon. Iron and Carbon are tweo different elements. So steel contains two different elements.
Iron is, itself, and element. It is not a compound of two elements.

The core of the earth contains many elements, not just two.However the two most abundant elements in the earth's core are nickle and iron (the final two elements that a star can make by fusion before it dies).But there are many other elements in the core, especially ones with atomic masses greater than that of nickel and iron. Many of these heavy elements are radioactive (e.g. radium, thorium, uranium) and it is the heat generated by the decay of these heavy radioactive elements that keeps the core hot and the outer core liquid.
Iron (Fe) and Sulfur (S) make up Iron Sulfide.
Iron & Bromine Its chemical formula is FeBr3
