Chemical change
chemical, e.g. if you have silver, and it tarnishes, the dark spots (the tarnished areas) are actually silver oxide. If it were a physical change, the silver would need to change states of matter. Into gas, liquid or plasma

Drawing it into a wire is a physical change of silver.
It is a chemical change. Oxygen from the air combined chemically with the silver to form silver oxide- that is the tarnish.

The tarnishing of silver is due to a reaction with hydrogen sulfide. Because the end result of the tarnish is silver sulfide, it is a chemical change.

It's called chemical weathering/chemical change. Similar to the physical change of matter, except the chemical composition changes causing it to become something completely different. For example: iron turns to rust, silver tarnishes and copper turns green.
