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, 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.
Transitional elements/metals.
Carbon, Oxygen, Sulphur, Iron, Hydrogen, Nitrogen as the main elements to be found in a tyre.
