Corrosion. Oxidation, combination of the surface atoms with oxygen, called rust in the case of iron, is one form of corrosion. Aluminum and many other metals oxidize. Combination with sulfur is also common, particularly for copper compounds. All metals except gold corrode in some fashion.

Is a metal surface being ground a chemical change?
A metal Surface being ground is a physical change, not a chemical change.
Is tarnishing of metal a physical or chemical change?
Yes. It is a reaction between the metal and oxygen.
Is electroplating a chemical or physical change?
Electroplating is a chemical change. Solutions containing metal ions are placed in a tank, and the piece of metal to be plated is connected to the electrical supply to become the cathode. The metal ions in solution are attracted to the cathode where they are reduced (reduction is gain of electrons) to form a metal coating.
Is a washer rusting a chemical change?
Yes, rusting/corrosion is oxidation of the metal and is a chemical change.
Is hammering copper metal a physical or chemical change?
It is a physical change because you are changing the shape of the metal.
Is a metal surface being ground a chemical change?
A metal Surface being ground is a physical change, not a chemical change.
Is tarnishing of metal a physical or chemical change?
Yes. It is a reaction between the metal and oxygen.
Is pounded metal a physical or chemical change?
Physical change
Is corrosion of a piece of metal chemical or physical change?
chemical change
Is bending a metal rod chemical or physical change?
Physical Change, the metal has the same chemical structure and only the shape of the bar has changed
Is bending metal sheets a chemical change?
No. It is a physical change because the chemical composition of the metal remains the same.
What is Heating up metal with a flame is that a physical or chemical change?
No, it is a chemical change. The metal oxide formed is a new substance.
Is corrosion of metals physical or chemical change?
It is a chemical change, where a chemical such as oxygen or chlorine combines with a metal, forming an oxide or chloride of that metal.
Is metal corroding a physical change or chemical change?
Corrosion is a chemical change
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.
Is rusting a metal physical change?
Metal rusting (corrosion) is a chemical change.
What change undergoes chemical change?
For example a chemical reaction with an alkali metal.
