Yes, because a new substance is formed; and there are actually two kinds of rusting: red and black.
Rusting occurs when iron (or steel, which is mostly iron) combines with oxygen. Water promotes the reaction, so keeping the metal completely dry (including nearly zero humidity air) or completely covered with a water-resistant coating is the recipe for keeping the iron or steel from rusting.
When rusting occurs in the air where plenty of oxygen is available, the rust formed is a reddish-brown compound called Iron (III) Oxide, Fe2O3. The equation for its formation is 4Fe + 3O2 ---> 2Fe2O3
When rusting occurs underground or underwater where the amount of oxygen available is reduced, the rust formed is a hard and brittle black compound called Iron (II) Oxide, FeO. The equation for its formation is 2Fe + O2 ---> 2FeO

Which one is a chemical change rusting of iron or melting of iron?
Rusting of iron is a chemical change because it involves a reaction with oxygen to form iron oxide. Melting of iron is a physical change because it does not involve a change in the chemical composition of the iron.
Is metal chair-rusts physical or chemical change?
The rusting of a metal chair is a chemical change. The iron is undergoing oxidation as it combines with oxygen to form iron oxide.
Rusting is chemical change?
Yes, rusting is a chemical change.
Is rusting a nail a physical change or chemical change?
A nail rusting is a chemical change. The chemical formula of the metal completely changes, adding oxygen to the formula. Iron changes from Fe to FeO2 , or to Fe2O3
Is rusting a phsyical change?
Rusting is a chemical change because under it iron goes under oxidation and oxidation is a chemical process. Also, a physical change can be reversed but a chemical change cannot and rusting cannot be reversed. Hence also rusting is a chemical change.
