All atoms of iron are characterized by having 26 protons in their nucleus, which defines their atomic number and distinguishes them as iron (Fe). This specific number of protons leads to a unique electron configuration and chemical properties that differentiate iron from all other elements. In contrast, atoms of other elements have different numbers of protons, resulting in distinct identities and behaviors. Thus, the atomic structure of iron sets it apart from all other elements in the periodic table.
elements
Not all elements are formed in stars. While many lighter elements, such as hydrogen and helium, were created during the Big Bang, heavier elements like carbon, oxygen, and iron are synthesized within stars through nuclear fusion. Additionally, elements heavier than iron are primarily formed during supernova explosions and through processes like neutron capture. Some elements, like lithium and beryllium, are also thought to be produced in cosmic ray spallation rather than in stellar processes.
Stainless Steel; all other choices are elements - stainless steel is a steel alloy (composite elements).
It is the elements heavier than iron that are formed in a supernova. All the heavier elements up through uranium appear when a star of sufficient mass collapses in a supernova event. These heavier elements, sometimes referred to as the trans-iron elements, appear in the collapse of a massive star. In this catastrophic event, the iron and silicon (and any other lighter elements) in the star are super compressed. The already hot conditions are made even hotter, and the available energy is sufficient to drive the fusion reactions that create the trans-iron elements.All the fusion reactions up through those that create iron are exothermic, and that means they release energy. The fusion reactions that create the trans-iron elements are endothermic, and that means energy has to be put into them. Only in the collapse of a star of sufficient mass is there enough energy to drive the fusion reactions that produce the trans-iron elements.See periodic table (iron is number 26).See related link.
Most of the other elements were formed in the cores of stars through nuclear fusion processes, while some heavier elements beyond iron are created in supernova explosions. These processes involve the fusion of lighter elements into heavier ones under extreme temperatures and pressures.
As with all elements past Iron & Nickel, Tin is formed only in supernova explosions.
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.

They all formed from minerals rich in the elements iron, magnesium, silicon, and oxygen.
elements
Hydrogen, some helium and less lithium are the result of the big bang. All the other elements are made inside the cores of stars, except for elements heavier than iron. All elements heavier than iron are created during supernova explosions.

Gold and silver - and indeed all the elements are not formed on any planet (though they may be found on planets). the elements Hydrogen and Helium were formed at the begining of the universe during the early stages of the big bang. Later all the other elements up to the mass of Iron were formed from hydrogen and helium in the cores of stars. The elements heavier than Iron are all formed in supernova explosions when big stars explode at the end of their lives. These explosions scatter these new heavy elements out into space where the eventually collapse to form new suns and the planets round these suns. Thus all the Gold and Silver found on earth were formed in dead stars and were part of the dusty disk that formed round our sun in its youth. This disk gave rise to all the planets and therefore there will be some Gold and Silver in all the planets. Elements are not formed on planets (Unless human intervention was involved). Heavy metals like Gold and Silver are formed through fusion inside of a star. As a result, gold and silver should be scattered throughout the universe.

All of them. A star begins to die when it creates Iron. Then it creates all the elements heavier than Iron. It has already created the elements lighter. Thus when the star explodes it spreads the elements it has created witch is all of them.
