Iron is formed in the final fusion burn of a dying star. After that it has no more fuel to burn and collapses to form either a white dwarf, neutron star, or black hole depending on its mass at the time it runs out of fuel.

Is iron likely to be formed in the sun?
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.
What physical property causes earth's core to be made up of heavier elements including metals such as iron and earth's crust to be made of lighter elements such as silicon?
Density.
What 2 elements make up rust?
Iron and oxygen
Is alloy an element?
No. Alloys are mixtures made up of elements like:steel- made up of iron and carbon. Iron and carbon are elements but steel isnt.
What solid iron is the earth made up of?
The earth's core is made up of the elements iron and nickel.
Is iron likely to be formed in the sun?
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.
What is formed from stars?
All elements up to Iron are produced by smaller stars. heavier elements (everything heavier then iron) are produced from larger stars when they go supernova.
How are elements formed from hydrogen?
Heavier elements are formed from hydrogen, the most abundant element in the universe, through a process called nuclear fusion. There are machines or structures in the universe that do this, and we call them stars. It is the process within stars, stellar nucleosynthesis, that allows heavier elements to be created up through iron. Elements heavier than iron are formed in supernova events.

Is metal made up of atoms?
Yes, all chemical elements - including metals - are formed from atoms.
Why is iron the heaviest element that can be formed in stars?
It isn't. Heavier elements are formed in stars as well. Iron is basically the heaviest element for which energy can be gained. When converting iron into heavier elements, energy is lost. However, this doesn't stop supernovae, at a temperature of about one gigakelvin (a billion degrees), to form heavier elements. In fact, the interior of stars is practically the ONLY way such elements can be formed.
What is the relationship between the periodic table and a supernova?
The elements on the periodic table were created by stars through nuclear fusion. We use the term stellar nucleosynthesis to describe what stars are doing through fusion. Stars fuse hydrogen into helium, and then start making heavier elements by a different fusion process. But stars can only make elements up through iron. They can't make the heavier elements. Enter the supernova. A supernova is that "big blast" that occurs at the end of the life of some stars. In a supernova, the trans-iron elements are formed. That is, all the elements heavier than iron are formed in a supernova. Because the elements heavier than iron are formed in a supernova, we can say that there is a relationship between the supernova and the periodic table of elements.
What physical property causes earth's core to be made up of heavier elements including metals such as iron and earth's crust to be made of lighter elements such as silicon?
Density.
What are the two elements that make up iron?
Iron is, itself, and element. It is not a compound of two elements.
What elements make up iron sulphide?
iron and sulfur
What 2 elements make up rust?
Iron and oxygen
What 2 substances contain iron?
No elements are made up of a compound. I think you mean 'Which elements make up iron oxide?', and the answer to that is iron and oxygen.
Is alloy an element?
No. Alloys are mixtures made up of elements like:steel- made up of iron and carbon. Iron and carbon are elements but steel isnt.
