There are three common naturally occurring forms of carbon: graphite, amorphous carbon, and diamond. These are used in many modern products including inks, rubber, steel, pencils, and more! Tens of millions of artificial carbon compounds are useful for petroleum (gasoline) and plastics.
What is carbon known for?
Carbon is most commonly obtained from coal deposits, although it usually must be processed into a form suitable for commercial use. Three naturally occurring allotropes of carbon are known to exist: amorphous, graphite and diamond.
Why carbon is important for us?
Carbon is an important constituent of living beings. Along with Nitrogen and oxygen, carbon is one of the essential building blocks of organic life. Carbon forms about 18% of the human body. Carbon is integral because of its unique ability to form four different bonds with other elements.
Impure carbon in the form of charcoal (from wood) and coke (from coal) is used in metal smelting. It is particularly important in the iron and steel industries. Graphite is used in pencils, to make brushes in electric motors and in furnace linings. Activated charcoal is used for purification and filtration.
Carbon, in the form of carbon dioxide, is used in the manufacture of many fizzy and carbonated drinks. It is also used in fire extinguishers. Dry ice, which is the solid form of carbon dioxide, is used as a cooling agent. Freon, is used in cooling systems and devices like refrigerators and air conditioners.
Carbon constitutes roughly 18 percent of body mass, and millions of carbon atoms form the thousands of molecules in virtually every cell. Carbon is the basic building block required to form proteins, carbohydrates and fats, and it plays a crucial role in regulating the physiology of the body.
Carbon is also found in the atmosphere where it's a part of carbon dioxide gas emitted when fossil fuels are burned and when living organisms breathe. It's in organic matter in the soil, and it's in rocks. But far and away the most carbon on Earth is stored in a surprising place: the ocean.
Interesting Facts about Carbon. About 20% of the weight of living organisms is carbon. More compounds are known which contain carbon than don't. Diamond is an excellent abrasive because it is the hardest common material and it also has the highest thermal conductivity.
Carbon dioxide is used to produce carbonated soft drinks and soda water. Large quantities of solid carbon dioxide (i.e. in the form of dry ice) are used in processes requiring large scale refrigeration. Carbon dioxide is also used in fire extinguishers as a desirable alternative to water for most fires.
Packaged carbon monoxide is used in a variety of industries for a wide range of applications including: Metal Fabrication: Used in fuel gas mixtures with hydrogen and other gases for industrial and domestic heating. Chemicals: In the manufacture of a variety of chemicals such as acids, esters and alcohols.
Wood contains carbon because it comes from a plant that once completed photosynthesis, taking in carbon dioxide to produce glucose and build its cell walls out of cellulose. Plastic is derived from petroleum, which contains hydrocarbons, compounds composed entirely of hydrogen and carbon.
Carbon is classified as an element in the 'non-metals' section which can be located in groups 14,15 and 16 of the Periodic Table. Non-metallic elements exist, at room temperature, in two of the three states of matter: gases (Oxygen, Hydrogen & Nitrogen) and solids (Carbon, Phosphorus, Sulfur and Selenium).
A lot of carbon combines with oxygen to make carbon monoxide (one oxygen atom) or carbon dioxide (two oxygen atoms), for example. All living things on Earth are made mostly of hydrocarbons(molecules of hydrogen and carbon) and water (molecules of hydrogen and oxygen).
Located between boron (B) and nitrogen (N), it is a very stable element. Because it is stable, it can be found both by itself and in many naturally occurring compounds. Scientists describe the three states of carbon as diamond, amorphous, and graphite. It is the same graphite you find in pencils.
Carbon dioxide plays an important part in vital plant and animal process, such as photosynthesis and respiration. These processes will be briefly explained here. Green plants convert carbon dioxide and water into food compounds, such as glucose, and oxygen. This process is called photosynthesis.
The physical and chemical properties of carbon depend on the crystalline structure of the element. Its density fluctuates from 2.25 g/cm³ (1.30 ounces/in³) for graphite and 3.51 g/cm³ (2.03 ounces/in³) for diamond. The melting point of graphite is 3500ºC (6332ºF) and the extrapolated boiling point is 4830ºC (8726ºF).
Let's start with how living things get carbon. Plants use carbon dioxide for photosynthesis. By doing so, they remove inorganic carbon from the atmosphere and incorporate it into the plants' tissues in the form of organic carbon (sugar and starch). Animals get carbon by eating plants or by eating other animals.
Carbon is found in abundance in the sun, stars, comets and atmospheres of most planets. Graphite is found naturally in many locations. Diamond is found in the form of microscopic crystals in some meteorites. Natural diamonds are found in the mineral, kimberlite, in South Africa, Arkansas and elsewhere.
Carbon is a chemical element, like hydrogen, oxygen, lead or any of the others in the periodic table. Carbon is a very abundant element. It exists in pure or nearly pure forms – such as diamonds and graphite – but can also combine with other elements to form molecules.
Carbon does not dissolve in or react with water, acids, or most other materials. It does, however, react with oxygen. It burns in air to produce carbon dioxide (CO 2 ) and carbon monoxide (CO).
The main use of sulfur is to make sulfuric acid, but it is also used as a fungicide and in medicine to treat certain skin conditions. for example, sulfur based concretes, cements and wall coatings are used where resistance to chemical attack is important. Large amounts of sulfur are used in the vulcanization of rubber.
By definition, an organic compound must contain at least one atom of carbon, but this criterion is not generally regarded as sufficient. With carbon bonded to metals the field of organic chemistry crosses over into organometallic chemistry.
Both of these are nutrient cycles, by which the nutrients (water and carbon) move across the various compartments of Earth. Both the cycles use plants as an integral component. Carbon cycle uses plants for uptake of CO2, by which it is removed from the atmosphere (and sent back to atmosphere when the plant is dead).
