Iron(III) oxide structure – Fe2O3


The above image explains the framework of the Iron(III) oxide. Fe2O3 is the chemical formula the Iron(III) oxide which has three oxygen atoms, two iron atoms. The oxidation state of Fe2O3 is +3. The bond formation between oxygen and iron depends on the distinction in electronegativity between these two atoms. Iron(Fe) is steel whereas oxygen(O2) is non-metal. Therefore, such bonds are referred to as an Ionic bond.
