COPPER
Physical and Chemical Properties: Physical and Chemical Properties:
Malleable-can be bent and shaped without cracking. Ductile-can be stretched out into a thin wire. Copper is very good at conducting electricity and heat, therefore, it is used in electrical wiring. Copper has a very low chemical reactivity.
Important Uses of Copper:
Copper is an extremely important metal used in refrigerators, radiators, cookware., and some electrical equiptment. The production of Copper has lifted, so the quantities of Copper in the enviornment have expanded greatly.
FUNFACTS! Did you know....the Statue of Liberty is made of 200,000 pounds of copper sheeting?!?! Did you know....Copper is the only metal other than gold that has natural color?!?! Did you know....Copper is used to make pennies, quarters, nickels, and dimes?!?!
Copper is resistant to corrosion and will not rust. If the air is damp, it will turn from reddish orange to reddish-brown, eventually being coated with a green film called patina, which stops all further corrosion. Melting point of Copper: 1083.4 degrees Centigrade. Liquid Copper Boiling Point: 2567 degrees Centigrade.
Copper: Cu Atomic Number: 29 Atomic Mass: 63.54
