= __**Copper at a Glance (Chemical and Physical Properties):**__ = Coppers atomic number is 29 and is one of three “money metals” on the periodic table. It has an extremely high melting point of 1083 degrees Celsius. Although Copper is not naturally very shiny, when polished it reflects a bright red-orange.

Copper is not a very reactive metal, but has a tendency to turn green over time when in contact with air this process is called oxidation. The green coating is called //Patina// and its purpose is to prevent the metal from corroding any further. Other than being malleable and ductile, copper is a great conductor, which is why it is used so often in heating and electricity.

A good look at how malleable copper can be! media type="youtube" key="3jSz11lz8MA" height="315" width="420"

__**Chemical and Physical Properties**__
> __**Use **__ Copper is believed to have been discovered by the Egyptians (3900 B.C.E.). Today, we use copper for many different purposes; we are able to use this metal for such a vast variety of purposes due to its specific chemical and physical properties, such as malleability and ductility, and conductivity.

Copper is used extensively in electrical wiring and circuitry. Gold contacts are sometimes found in precision equipment for their ability to remain corrosion-free. It is used for water pipes and plumbing, currency, electric wires, heating, construction, in alloys such as bronze or brass, protective coatings like in nickel and zinc, utensils and even in animal feeds and fertilizers as a micronutrient, it is also an antifungal. Copper is also used in deodorant! So think of how much you love copper when you're standing next to a big sweaty man on the airplane! Copper is a very good conductor of electricity and heat which is a result of coppers low hardness, as well as it's ductility and malleability is attributed to its weak bonds. It is therefore substituted for aluminum in many circuits and machines. Copper is easily combined with other elements, creating many different alloys used in many businesses such as in the jewelry business. Combining copper with other metals alters its characteristics, for example it changes the melting point of the original metal. Copper is also water resistant, which is why it is used for plumbing and roofing. As a conductor of heat and electrical energy it is second only to silver, but silver is very expensive.

=__ **WHY SHOULD YOU BUY COPPER?!** __=

**find out why sally decides to buy this super cool element from eric, in this original and funny commercial! (watch parts 1-4 in order please!)**
**directed by Caroline and produced by Bingyan** **starring Caroline and Bingyan!**

Are you tired of buying overpriced, and processed copper materials that are only good for one thing? why buy an expensive copper pipe? When you could buy copper in it's natural form and have the ability to make it into anything!!! If you buy natural copper at whole sale prices you can save thousands! millions! you will never again have to buy wires, heaters, pipes, deodorant, jewelry and more! media type="custom" key="12115924"

=__** Cost **__= As mentioned in our commercial, the cost of copper on atomazon.com is normally $200 per pound, however, we will sell it at half price to you!!!! $100 dollars per pound! limited time offer. if you wish to purchase the element and the helpful instruction manual the cost is $150! Happy shopping!

= **Comparison to similar elements** =

The metals, copper, silver and gold are all found in Group 11 of the periodic table and share certain attributes: they have one s-orbital electron right above a full d shell. All of these metals are characterized by a high ductility, thermal conductivity and electrical conductivity. aluminum applies here too. copper is also similar to osmium and gold because those three elements are the only metals with a natural color. all other metals are naturally silver colored. gold is yellow and osmium is bluish. the color of copper comes from the electrons moving up and down in the 3d and the 4s shells. when an electron moves down an energy level, it gives off light. The light copper gives out corresponds with orange.

need more info on how its similar to other elements! ^

Copper is a natural antibacterial, which is why water and air distribution systems are made from it. This is also the reason you will find many brass (alloy containing copper) doorknobs in public buildings.
