Group 11 element. Group 11, by modern IUPAC numbering, is a group of chemical elements in the periodic table, consisting of copper (Cu), silver (Ag), and gold (Au). Roentgenium (Rg) is also placed in this group in the periodic table, although no chemical experiments have yet been carried out to confirm that it behaves like the heavier homologue to gold.
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.It is used as a conductor of heat and electricity, a building material, and a constituent of various metal alloys.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.
