oxidation
Metal rusting (corrosion) is a chemical change.
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.

Another name for melted metal is molten metal.
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.

Zinc Oxide can be used to protect iron hulls from rusting.
This metal is zinc (Zn).
