Copper is a chemical element with symbol Cu (from Latin: cuprum) and atomic number 29. It is a ductile metal with very high thermal and electrical conductivity. Pure copper is soft and malleable; a freshly exposed surface has a reddish-orange color.here are 29 isotopes of copper. 63 Cu and 65 Cu are stable, with 63 Cu comprising approximately 69% of naturally occurring copper; they both have a spin of 3â2. The other isotopes are radioactive, with the most stable being 67 Cu with a half-life of 61.83 hours.
