Iron is not a molecular solid. It's a metallic element, and as such doesn't really have "molecules." In a sense, the entire mass of iron can be thought of as one big molecule which contains ... well, iron.
The elements found in ferrous oxide are iron (Fe) and oxygen (O).
iron is found in mixed form with other elements in a compound, mainly it is found as iron oxide
iron is found in mixed form with other elements in a compound, mainly it is found as iron oxide
The five chemical elements commonly found in pig iron are iron, carbon, silicon, manganese, and phosphorus.
If you mean iron pyrophosphate, its formula is Fe4(P2O7)3, which means it contains the elements iron, phosphorus and oxygen.
Iron sulfates contain iron, sulfur and oxygen.
Iron (Fe) and Sulfur (S) make up Iron Sulfide.
Iron is NOT made up of two elements. Iron is an element in its own right. It is found in the Periodic Table of Elements as 'Fe'. 'Fe' is the initials of the Latin name for iron, which is Ferrum. However, iron is mined as iron ore, which is an oxide of iron. It is a chemical combination of iron and oxygen. These are possibly the two elements you are thinking about. As oxides of iron can be found in different forms ( oxidation states). They Are. :- Fe3O4 ; Magnetite. (Lodestone of early navigation). Fe2O3 ; Iron (III) Oxide [ Ferric oxide) the common iron ore. FeO ; Iron (II) Oxide (Ferrous oxide) FeS ; Iron (II) Sulphide (Much less common. Iron metal is NOT found uncombined.
Iron, carbon, copper, lead,
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.
Most iron ores are iron oxides or iron sulfides. Iron ores are also usually hydrated (i.e. includes water of crystallization). A variety of other metal ores (e.g. copper, zinc, lead) are sometimes mixed with iron ores. In much lower concentrations, almost any element (except the inert gases) might be found.
