Rust as seen on the surface of iron/steel is a physical entity ; a solid.
. It is iron oxide.
It has become rust by a chemical reaction. Iron has reacted with oxygen(air) (& Water is present ) to form rust .
2Fe (s) + 3O2 = Fe2O3(s)
Iron has several oxides viz. FeO, Fe2O3, Fe3O4
FeO ( Iron(II) Oxide/ Ferrous Oxide) is a solid , green in colour and readily oxides to Fe2O3 .
Fe2O3 ( Iron(III) Oxide/ Ferric Oxide) is a solid, red/brown in colour and stable( does not readily reduce in the air).
Fe3O4 (Magnetite) is a dark coloured solid, stable at room temperatures , and was the 'lodestone' of viking navigators. As the name suggests it responds to magnetic fields.
