Iron – Heavy Metal. Iron is a chemical element in the periodic table that has the symbol Fe and atomic number 26. Iron is a group 6 and period 4 metal. Iron is notable for being the final element produced by stellar nucleosynthesis, and thus the heaviest element which does not require a supernova or similarly cataclysmic event for its formation.


Carbon is more reactive than iron, so it can push out or displace the iron from iron oxide. Here are the equations for the reaction: iron oxide + carbon → iron + carbon dioxide 2Fe 2 O 3 + 3C → 4Fe + 3CO 2. In this reaction, the iron oxide is reduced to iron, …


This is even harder than pig iron. Wrought Iron/ Malleable Iron. Wrought iron is the purest form of iron available commercially available and is prepared from cast iron by heating cast iron in a furnace lined with Haematite (Fe 2 O 3). The Haematite reacts with Carbon in the cast iron to give pure iron and carbon monoxide gas which escapes.
