Assuming the metal is ferrous(contains iron) then rusting represents a chemical change because the metal (in the presence of water and oxygen) is changed into a different compound, Fe2O3. Since we started with an iron containing metal and we now have Fe2O3 which is not the same substance, a chemical change must have occurred.

What transition metal rusts when exposed to oxygen?
Iron is the transition metal that rusts when exposed to oxygen, forming iron oxide.
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.
When an old car sits in a junk yard and rusts is it a chemical change?
Rusting of a metal, be it a car or any other item, represents an oxidation reaction, and this is a chemical change because the metal is becoming a metal oxide in the process.
Is iron rusts a physical or chemical change?
Its is chemical as
Is corroding metal a chemical change?
Yes, corroding metal is a chemical change because it involves a chemical reaction between the metal and substances in its environment, such as oxygen or water. This reaction causes a change in the composition and properties of the metal.
Is metal corroding chemical change?
Yes. When metal rusts the iron is changed into iron oxide. This type of change is called a redox reaction. The iron is oxidized, meaning is has lost electrons.
