Metal rusting (corrosion) is a chemical change.
Some ways to prevent rusting include using rust-resistant materials like stainless steel, applying protective coatings like paint or zinc plating, keeping metal surfaces dry and well-ventilated, and using rust inhibitors or desiccants to absorb moisture. Regular maintenance and cleaning can also help prevent rust from forming.
Rusting
It depends on what metal is 'rusting'.
When rusting occurs, some of the outer metal converts to a crumbly iron oxide that doesn't have the same strength as the metal. The deeper the rusting goes into the metal , the weaker the bar will become.

To prevent or slow down rusting on galvanized metal, you can apply a protective coating such as paint or a clear sealant. Regularly inspect the metal for any signs of damage or wear, and promptly repair any scratches or chips in the coating to prevent rust from forming. Additionally, keeping the metal clean and dry can help prevent rust from developing.
If by non rusting you mean it is in the same state it was made in then it wouldn't be part of any change. But if something is rusting it would be a chemical change because the metal is changing composition and it is not the same metal it was in the first place.
It will keep the metal from rusting.
Rusting is the oxidation of a metal and is an example of a chemical change.
