Lab: size of the atom
... Galvanized iron is produced by coating iron with a thin layer of metallic zinc. The zinc coating protects the underlying iron metal against rusting or corrosion. Zinc is more reactive than iron and thus reacts with oxygen in the air and with water before the iron'does. In this way, the zinc coating ...

The production and use of metals
... The more reactive a metal, the more stable are it’s compounds and therefore the more difficult they are to extract. Iron is a fairly reactive metal. It is found as an ore called haematite which is mainly iron oxide mixed with impurities. Iron is extracted in the Blast Furnace (Port Talbot Steelwork ...
