ChemSpider is a free chemical structure database Glossary Image explanation Murray Robertson is the artist behind the images which make up Visual Elements. This is where the artist explains his interpretation of the element and the science behind the picture.
Appearance The description of the element in its natural form. Biological role The role of the element in humans, animals and plants. Natural abundance Where the element is most commonly found in nature, and how it is sourced commercially. Appearance There are a number of pure forms of this element including graphite, diamond, fullerenes and graphene.
Diamond is a colourless, transparent, crystalline solid and the hardest known material. Graphite is black and shiny but soft. The nano-forms, fullerenes and graphene, appear as black or dark brown, soot-like powders.
Uses Carbon is unique among the elements in its ability to form strongly bonded chains, sealed off by hydrogen atoms. These hydrocarbons, extracted naturally as fossil fuels coal, oil and natural gasare mostly used as fuels. A small but important fraction is used as a feedstock for the petrochemical industries producing polymers, fibres, paints, solvents and plastics etc.
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. It is found in respirators and kitchen extractor hoods. Carbon fibre is finding many uses as a very strong, yet lightweight, material. It is currently used in tennis rackets, skis, fishing rods, rockets and aeroplanes.
Industrial diamonds are used for cutting rocks and drilling. Diamond films are used to protect surfaces such as razor blades.
The more recent discovery of carbon nanotubes, other fullerenes and atom-thin sheets of graphene has revolutionised hardware developments in the electronics industry and in nanotechnology generally.
Inas a result of combusting fossil fuels with oxygen, there was ppm. Atmospheric carbon dioxide allows visible light in but prevents some infrared escaping the natural greenhouse effect.
This keeps the Earth warm enough to sustain life. However, an enhanced greenhouse effect is underway, due to a human-induced rise in atmospheric carbon dioxide. This is affecting living things as our climate changes. Biological role Carbon is essential to life. This is because it is able to form a huge variety of chains of different lengths.
It was once thought that the carbon-based molecules of life could only be obtained from living things.
However, inurea was synthesised from inorganic reagents and the branches of organic and inorganic chemistry were united.
Living things get almost all their carbon from carbon dioxide, either from the atmosphere or dissolved in water. Photosynthesis by green plants and photosynthetic plankton uses energy from the sun to split water into oxygen and hydrogen. The oxygen is released to the atmosphere, fresh water and seas, and the hydrogen joins with carbon dioxide to produce carbohydrates.Magnesium is a dietary mineral.
Magnesium deficiencies are the second most common deficiency in developed countries, the first being vitamin D.A lack of magnesium will raise blood pressure and reduce insulin sensitivity.
There remains growing interest in magnesium (Mg) and its alloys, as they are the lightest structural metallic materials. Mg alloys have the potential to enable design of lighter engineered systems, including positive implications for reduced energy consumption.
The Proline fry pan is ideal for preparing delicate dishes like eggs, omelets, and fish, and for a variety of cooking techniques such as sautéing, braising, baking, and frying with or without fat, thanks to its proprietary construction. Thermocouple is a pair of dissimilar metal wires joined at one end, which generate a net thermoelectric voltage between open pair according to the temperature difference between the ends.
