Copper

Copper, the 29th element, is a metal. In industry it is praised for its extreme ductility and electrical conductivity which make it an excellent material for wires. Copper is also a nutrient mineral, and is required by the human body to perform certain chemical reactions.

Copper is also important culturally, as one of the first metals to be used by humankind, especially in its alloy form bronze. Even today the pennies in the United States are informally referred to as "coppers."

The atomic symbol for copper, Cu, comes from the Latin cuprum which also gives its name (via Greek) to Cyprus, an island nation in the Mediterranean renowned for its wealth of copper.
