What is Rust
Rust is the common name for a very common compound, iron oxide. Iron oxide, the chemical Fe2O3, is common because iron combines very readily with oxygen -- so readily, in fact, that pure iron is only rarely found in nature. Iron (or steel) rusting is an example of corrosion-- an electrochemical process involving an anode (a piece of metal

While iron can have oxidation states ranging from − 4 to + 7, its most common oxidation states are + 2 and + 3. When forming ions, iron will lose two electrons from the 4s subshell, but it can also lose a third electron from its paired 3d orbital resulting in a + 3 oxidation state.
