Rust is oxygen and iron, not just iron. (The guy who said "air and iron" was basically right, but it is the oxygen in the air that combines with the iron. Other stuff in air, like nitrogen, isn't part of rust.)

Rust is iron oxide.
The iron gained oxygen molecules

Corrosion is oxidization. Oxygen is added to the iron molecules

Fe + O2 >>> Fe3o4
You see now added the Oxgeon to Fe. Now heavier
