Atomic Number: 6
Atomic Weight: 12.0107
Date of Discovery: Known to the ancients
Physical Properties:

Carbon is a soft, dull gray or black non-metal that you can scratch with a fingernail.
The density of carbon as graphite is 2.267 g/mL, which means it will sink in water. Chemical Properties:
Carbon, as graphite, burns to form gaseous carbon (IV) oxide (carbon dioxide). When the air or oxygen supply is restricted, incomplete combustion to carbon monoxide, CO, occurs.
In industry, water is blown through hot coke. The resulting gas is called water gas and is a mixture of hydrogen (50%), carbon monoxide (40%), carbon dioxide ( 5%), nitrogen and methane (5%). It is an important feed stock gas for the chemical industry and an important source of hydrogen gas. Hydrogen gas is also made from methane and water in a similar reaction.
Carbon in organic or hydrocarbon compounds is the foundation of modern society and biochemistry. Carbon, oxygen, and hydrogen are the most important elements.

Copper is commonly used to transfer electricity, due to its high thermal and electrical conductivity. Electrons move freely between copper atoms. Copper has a germicidal effect meaning that many germs are neutralized by it. This is why it is often used in things like doorknobs because of its automatic disinfecting qualities. This is also why copper was used in ancient days to treat wounds. In addition to these qualities, copper is found in many household items like piping, lightning rods, and cooling units (refrigerators, air conditioners, etc.), due to its excellent thermal conductivity. These are just some of many modern uses of copper.
Copper is one of the basic known elements; its symbol is Cu on the periodic table of elements. Its atomic number is 29. It is a soft metal that can bend and form into to shapes, and can be pounded into thin sheets without fracturing. It has a pinkish-brown color ideal for use in jewelry. It isn’t just used in fashion but it is used to transmit high electrical and thermal conductivity. It is the second most conductible metal under silver. It is used in Electrical wires within our homes. Silver is the most conductible metal but the price is a factor that lowers the
