Carbon

BY: DURELL RUSSELL

DISCOVERY

Carbon is also the key ingredient for most life on Earth; the pigment that made the first tattoos; and the basis for technological marvels such as graphene, which is a material stronger than steel and more flexible than rubber.

Carbon occurs naturally as carbon-12, which makes up almost 99 percent of the carbon in the universe; carbon-13, which makes up about 1 percent; and carbon-14, which makes up a minuscule amount of overall carbon but is very important in dating organic objects.

Carbon is a chemical element with a symbol C and a atomic number 6. It is the first of six elements in column 14, which the compsition of theire outter shell.

Symbol C atomic 6 it was the first discovered as charcal in the pre historic times.It wasant reconized as a element until the seventeeth century it is unkown who discovered it. Boyle defined what a element was lavoisier named carbon as a elment. in 1985 a new form of carbon was dicoverd called buckyball. which is a hollow spherical molecue composed of a large amount of carbon atoms.

the pyical properties are•*Allotropic: Two allotropes of carbon have different crystalline structures: diamond and graphite. The physical properties of carbon vary widely with the allotropic form.•Forms of Carbon: Graphite, diamonds and coal are all nearly pure forms of carbon•Color: Diamond is highly transparent. Graphite is opaque and black•Hardness: Diamond is one of the hardest substances known to man. Graphite is soft and often used as the "lead" in lead pencils•Conductivity: Diamond has a very low electrical conductivity. Graphite is a very good conductor•Brittleness: Very brittle, and cannot be rolled into wires or pounded into sheets•Phase: Solidthe chemical properties are•Chemical Formula: C•Oxidation: Combines with oxygen to produce carbon dioxide (CO2 ) and carbon monoxide (CO)•Reactivity: Carbon does not dissolve in, or react with, water or acids•Chains of Atoms: Carbon has the ability to make long strings, or chains, of atoms•Compounds: Carbon forms more compounds than all other elements combined; several million carbon compounds are known•Buckminsterfullerene - C60: Carbon also occurs in a newly discovered form known as fullerenes or buckyballs. A fullerene is any molecule composed entirely of carbon. Fullerenes are similar in structure to graphiteboling point-4,827°C melting point-3550 density-: 2.2670 grams per cubic centimetercolor-black (graphite), transparent (diamondtype of element-graphite

Carbon is a pattern maker. It can link to itself, forming long, resilient chains called polymers. It can also bond with up to four other atoms because of its electron arrangement. Atoms are arranged as a nucleus surrounded by an electron cloud

Carbon makes up 0.032 percent of the Earth's lithosphere (crust and outer mantle) by weight.A rough estimate of the weight of the lithosphere by La Salle University geologist David Smith is 300,000,000,000,000,000,000,000 (or 3*10^23) pounds, making the approximate weight of carbon in the lithosphere 10,560,000,000,000,000,000,000 (or 1.056*10^22) pounds.

Diamond, the flashiest version of carbon, is formed under great pressure deep in the Earth's crust. The largest gem-quality diamond ever found was the Cullinan diamond, which was discovered in 1905, according to the Royal Collection Trust. The uncut diamond was 3,106.75 carats. The largest gem cut from the stone, at 530.2 carats, is one of the Crown Jewels of the United Kingdom and is known as the Great Star of Africa.

About 20% of the weight of living organisms is carbon.Pure carbon is considered non-toxic, although inhalation of fine particles, such as soot, can. Carbon is a nonmetal that can bond with itself and many other chemical elements, forming nearly ten million compounds. Carbon is made in the interiors of stars, though it was not produced in the Big Bang.

The origin of the name 'carbon' comes from the Latin word carbo, for charcoal. The German and French words for charoal are similar.
