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.
Iron is not formed in the Sun through nuclear fusion. Iron is the element with the highest nuclear binding energy per nucleon, making it less energetically favorable for fusion reactions to produce iron in the Sun. Iron is typically formed in the later stages of a massive star's life during a supernova explosion.
The heavier elements in the universe were primarily formed through processes such as stellar nucleosynthesis and supernova explosions. In stars, nuclear fusion combines lighter elements like hydrogen and helium into heavier elements up to iron. Elements heavier than iron are typically formed during supernovae, where the intense energy and neutron capture processes create these elements. Additionally, some heavy elements may also form through the merging of neutron stars.
Most natural elements are formed in stars through nuclear fusion processes. In the cores of stars, hydrogen atoms fuse to create helium and, in larger stars, heavier elements up to iron are produced. Elements heavier than iron are typically formed during supernova explosions, where the intense energy allows for the fusion of heavier nuclei. Additionally, some lighter elements are formed in processes like cosmic ray spallation and during the Big Bang nucleosynthesis.

Iron is not formed in the Sun through nuclear fusion. Iron is the element with the highest nuclear binding energy per nucleon, making it less energetically favorable for fusion reactions to produce iron in the Sun. Iron is typically formed in the later stages of a massive star's life during a supernova explosion.
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.
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.
Iron is, itself, and element. It is not a compound of two elements.
Elements heavier than hydrogen are formed through nuclear fusion processes in stars. When lighter elements fuse together in the intense heat and pressure within a star's core, they can form heavier elements. This process continues throughout a star's life until elements up to iron are created. Elements heavier than iron are formed through supernova explosions or in the collisions of neutron stars.
Yes, all chemical elements - including metals - are formed from atoms.

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.

Elements heavier than hydrogen and helium primarily formed in the cores of stars through nuclear fusion processes. Elements up to iron are formed in the cores of stars, while elements heavier than iron are typically produced in supernova explosions or neutron star mergers. These heavy elements are dispersed into space during these catastrophic events, enriching the interstellar medium from which new stars and planets can form.
