Copper (Cu) By: Kerri King, Denise Gettermann and Heather Castrillon


3 Discovery of Copper There is no known discoverer of Copper.
People have been using Copper for at least 11,000 years. Cuprum is the word for copper in Latin because they used to mine their copper from the island of Cyprus About 7,000 years ago people began to find ways to extract copper from its ores

4 Characteristics of Copper
Transition Metal Atomic Number: 29 Atomic Weight: Melting Point K( C or F) Boiling Point 2835 K ( 2562C or 4644F) Density: grams per cubic centimeter Phase at Room Temperature: Solid Element Classification: Metal

5 Characteristics (continued)
Period Number: 4 Group Number: 11 Ionization Energy: eV Oxidation States: +2, +1 Number of stable Isotopes: 2 Estimated Crustal Abundance:6.0×10-1 milligrams per kilogram Estimated Oceanic Abundance: 2.5×10-4 milligrams per liter It is a reddish-colored metal Has a high electrical and thermal conductivity

6 Source of Copper Copper is found in places such as the United States, Chile, Zambia, Peru, Canada and Great Britain Mines

7 Uses of Copper Copper is used for various reasons. These reasons include: Making pipes Making jewelry Electrical conductor coins Pure Copper is often to soft to be used. About 5,000 years ago, people began to realize that it is stronger if it is mixed with other elements. Alloys of copper commonly used are Bronze Brass

8 Uses of Copper continued)
Household Products: Doorknobs Roofing Gutters Cookware-- frying pans Flatware (knifes, forks, spoons) Sterling silver always has a percentage of copper Coins American pennies are coated with copper but made from zinc (.8% copper, 99.2% zinc) U.S. nickels 75% copper ( 25% nickel) by weight U.S. dimes and quarters are 91.67% copper and 8.33% nickel by weight
