Copper has been known since prehistoric times and is named 'Copper' Latin word "cyprium", after the island of Cyprus .

Some common usages for Copper: electrical conductor, jewelry, coins and plumbing.

Definitions and Notes

Density listed is at a temperature of 20°C.

Isotopes are forms of an element who have the same atomic number but different mass because they contain different number of neutrons.

Half-life is the time required for a quantity of a subject to fall to half of its current quantity.
