Rust is an iron oxide, a usually reddish-brown oxide formed by the reaction of iron and oxygen in the catalytic presence of water or air moisture.Rust consists of hydrous iron(III) oxides (Fe 2 O 3 ·nH 2 O) and iron(III) oxide-hydroxide (FeO(OH), Fe(OH) 3), and is typically associated with the corrosion of refined iron. Rust is a compound (Fe2O3). Air is a mixture -- it has oxygen (O2), nitrogen (N2), carbon dioxide (CO2) and a whole slew of other things. Helium is an element -- it's 1.
