What chemical element has the symbol Cu, an atomic number 29, and is known for being a dense, malleable and ductile metal with very high thermal and electrical conductivity?

Copper is one of the few metallic elements with active 3-dimensional covalent bonds. Metallic copper is found in nature, although, as an ore, native copper occurs in a limited supply. Pure copper is extremely rare in its native form because it must be extracted from its natural occurrence as a mixture of minerals such as chalcocite and native copper sulfides. In nature, its abundance is limited by abiotic factors such as the density of the ore and geological conditions.
