In the universe they are initially made in supernova explosions. These then become parts of other stars, planets and celestial bodies. Some are radioactive and decay into daughter elements which are usually after iron.
Iron is, itself, and element. It is not a compound of two elements.
Iron sulfide (FeS) consists of two elements: iron (Fe) and sulfur (S).
Iron fluoride is made up of iron (Fe) and fluoride (F) elements. Iron has a +2 oxidation state, while fluoride has a -1 oxidation state, so the chemical formula for iron fluoride is FeF2.
NO!!!! It is a COMPOUND, made up (COMBINATION) of two elements , viz. Iron and Oxygen. Compounds of iron and oxygen are : = FeO ; Ferrous Oxide Fe2O3 ; Ferric Oxide Fe3O4 ; Magnetite.
A cast iron skillet is not an element or a compound. It is an object made of a mixture of elements, primarily iron with small amounts of carbon and other trace elements.
Iron is, itself, and element. It is not a compound of two elements.
Iron sulfide (FeS) consists of two elements: iron (Fe) and sulfur (S).
No. Alloys are mixtures made up of elements like:steel- made up of iron and carbon. Iron and carbon are elements but steel isnt.
Up to uranium elements are made by stellar nuclear synthesis; after uranium elements are man made.
Iron fluoride is made up of iron (Fe) and fluoride (F) elements. Iron has a +2 oxidation state, while fluoride has a -1 oxidation state, so the chemical formula for iron fluoride is FeF2.
solid iron and nickelit is made up of IRON Nickel and other LIGHTER ELEMENTS
No. Iron is a single element. To be alive it would have to be made of many elements.
No. Copper and Iron are both elements and are made up of atoms of the pure element.
NO!!!! It is a COMPOUND, made up (COMBINATION) of two elements , viz. Iron and Oxygen. Compounds of iron and oxygen are : = FeO ; Ferrous Oxide Fe2O3 ; Ferric Oxide Fe3O4 ; Magnetite.
Iron is an element. It isn't "made". Iron is obtained by digging iron ore out of the ground (mining) and processing it to separate the iron from oxygen, sulfur and other elements to which it had become chemically bound over the millennia. According to modern astronomy, cosmology, and physics, iron, like all naturally occurring elements, is made in stars, from the fusion of smaller elements. Fred Hoyle proposed what's called 'nucleogenesis', or formation of elements in the stars. Hydrogen plus Hydrogen makes Helium; then on to Lithium, Carbon, Nitrogen, etc. Iron is the last element a 'normal' star can make. All elements heavier than Iron are made in the explosion of a supernova.
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.
Lead is a compound element that is made up of elements in the carbon group. It has the element maker of Pb. Lead at may contain trace elements of iron but it is not a major component.
