Rusting is the process in which iron turns into iron oxide. It happens when iron comes into contact with water and oxygen. The process is a type of corrosion that occurs easily under natural conditions.
Rust is the product of a chemical reaction in which iron oxidizes in the presence of an electrolyte. In order to form iron oxide, exposed iron must bond with oxygen, which usually happens when the iron surface gets wet.
Rust forms on iron due to an oxidation reaction that occurs when it comes into contact with oxygen and water. The reaction of iron, oxygen and water forms hydrated iron(III) oxide, which is known as rust. Acid rain or saltwater can cause iron to rust more quickly.

The elements found in rust are iron and oxygen. Rust has a chemical formula of Fe2O3.
Not all metal rusts, but the metals that do rust do so because of an oxidation reaction between the metal and water and oxygen. Oxidation is the process by which a substance incorporates oxygen into its molecular structure.
Rust on metal is caused by surface metal atoms and molecules forming metal oxides in the presence of oxygen and water. Iron is the most common material that rusts, forming iron oxides, but most other metals can rust as well.
Many metals oxidize and corrode, but rust, or iron oxide, is specific to ferrous metals such as steel. Rust is formed when oxygen bonds with an atom of iron to form an iron oxide molecule. This molecule is considerably larger than the surrounding iron molecules, so it quickly becomes dislodged and f
