Naturally occurring graphite occurs in two forms, alpha and beta.
These two forms have identical physical properties but different crystal structures.
Carbon is unique in its chemical properties because it forms a number of components superior than the total addition of all the other elements in combination with each other.
The biggest group of all these components is the one formed by carbon and hydrogen.
History and Uses: Carbon, the sixth most abundant element in the universe, has been known since ancient times.
Amorphous carbon is formed when a material containing carbon is burned without enough oxygen for it to burn completely.
This black soot, also known as lampblack, gas black, channel black or carbon black, is used to make inks, paints and rubber products.
It can also be pressed into shapes and is used to form the cores of most dry cell batteries, among other things.
They focused the sun’s rays on the diamond with a remarkable giant magnifying glass and saw the diamond burn and disappear.Graphite, one of the softest materials known, is a form of carbon that is primarily used as a lubricant.Although it does occur naturally, most commercial graphite is produced by treating petroleum coke, a black tar residue remaining after the refinement of crude oil, in an oxygen-free oven.Atomic Number: 6 Atomic Weight: 12.0107 Melting Point: 3823 K (3550°C or 6422°F) Boiling Point: 4098 K (3825°C or 6917°F) Density: 2.2670 grams per cubic centimeter Phase at Room Temperature: Solid Element Classification: Non-metal Period Number: 2 Group Number: 14 Group Name: none What's in a name? Three naturally occurring allotropes of carbon are known to exist: amorphous, graphite and diamond. Carbon is most commonly obtained from coal deposits, although it usually must be processed into a form suitable for commercial use.
