Rusting is the iron oxide that covers metal objects, therefore it is not included as a physical change.
It is commonly called oxidation chemical reactions in which oxygen combines with other substances, forming molecules called oxides.
In chemistry oxidation is called the chemical phenomenon in which an atom, molecule or ion loses one or more electrons, thus increasing its positive charge.
The physical changes of metals are changes that alter its shape without modifying its composition, this includes polishing, melting, bending, among others.
Therefore, we can conclude that the rusting of a metal corresponds to a chemical change due to the fact that it alters the molecular composition of said metal.
