Rust forms when metals containing iron mix with the oxygen in the air or the water and create a compound named iron oxide. This compoumd has water molecules, so we call it a hydrated compound. Chemically and very simply speaking, iron atoms lose a few electrons to oxygen atoms. This process, where electrons are lost from atoms, is the oxidation process. When oxidation occurs it produces a chemical reaction that creates iron oxide

The oxygen and water vapour react, salt speeds this up. Have you ever seen any bridges that rust? That is because they tower over salt water.

Oxygen+Water vapour->rust

When Iron and Oxygen mix. This happens easier in water than air because air is only about 27% oxygen and water is around 33% oxygen.

'Rust' is the everyday name for Iron Oxide (Fe2O3).

It forms when iron is in contact with both air and water.
