wire?
A. It conducts electricity when lightning strikes it.

Chemical properties are those properties that are not always shown physically, but they came out of a chemical reaction. Chemical properties are pH, solubility, toxicity, the heat of combustion, flammability, reactivity, etc.

The copper wire, when left out in the environment, becomes tarnished, due to the air and moisture present in the environment. The meaning of tarnished means it loses its luster or its quality.

Copper is a shiny, soft, and brown-colored metal. It is usually used in making wire used for electricity.
