Cu2O (copper(I) oxide)

Copper(I) oxide (Cu₂O) is a chemical compound composed of copper and oxygen atoms. It appears as a reddish-brown powder or crystal and is known for its stability and semiconducting properties. Cu₂O is used in applications like photoreactive surfaces, antifouling paints, and as a component in some solar cells. It forms when copper reacts with oxygen under specific conditions. Its chemical structure features copper in a +1 oxidation state, meaning it has lost one electron, which influences its electrical and chemical behavior. Overall, Cu₂O is a stable, useful material with valuable properties in technology and industry.
