Overview

Copper is a reddish, ductile transition metal prized for excellent electrical and thermal conductivity and antimicrobial properties.

Properties

It forms stable +1 and +2 oxidation states, alloys readily bronze, brass and resists corrosion in many environments.

Occurrence and Uses

Copper is mined from sulfide and oxide ores and used in electrical wiring, electronics, plumbing, roofing and as an essential trace nutrient.

Isotopes and Safety

Stable isotopes Cu 63 and Cu 65 exist; copper is essential biologically but excessive exposure can cause toxicity and environmental concerns.
