Metal rusting is a piece of metal such as a bike, and you leave it out in the rain. In a couple weeks, (If it's still out there,) it will be rusty. Rusty is a brown hard piece that sticks to metal. You need a scraper and a spare hour it your planning on getting it off.
The actual process is oxidization. Iron (Fe) becomes rust by having oxygen attach to the molecular structure (FeO2). Rust is about 50% heavier than the original metal.
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.

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.
oxidation
Yes
This metal is zinc (Zn).
Oxidation (rusting) of iron metal is the reaction of iron and oxygen
