Ferrous oxide is also called Iron (II) oxide with the chemical formula of FeO in which the oxidation state of Iron is +2. Rust is formed when iron (or an alloy of iron) is exposed to oxygen in the presence of moisture. However, in the case of rust, the iron atom gets converted to iron oxide (rust) due to the action of water and oxygen, and the oxide layer of iron once formed cannot be converted back into iron. The following reaction occurs: Fe + O 2 Fe 2 O 3. It belongs to the d-block of the periodic table with the atomic number 26. The process of depositing zinc on the iron to prevent rusting is known as galvanization.
