Carbon

Carbon is nonmetallic and tetravalent-making four electrons available to form covalent chemical bonds. The major economic use of carbon other than food and wood is in the form of hydrocarbons, most notably the fossil fuel methane gas and crude oil (petroleum). Crude oil is used by the petrochemical industry to produce, amongst others, gasoline and kerosene, through a distillation process, in refineries. Cellulose is a natural, carbon-containing polymer produced by plants in the form of cotton, linen, and hemp. Cellulose is mainly used for maintaining structure in plants. Commercially valuable carbon polymers of animal origin include wool, cashmere and silk. Plastics are made from synthetic carbon polymers, often with oxygen and nitrogen atoms included at regular intervals in the main polymer chain. The raw materials for many of these synthetic substances come from crude oil. It can form alloys with iron, of which the most common is carbon steel. Graphite is combined with clays to form the 'lead' used in pencils used for writing and drawing. It is also used as a lubricant and a pigment, as a molding material in glass manufacture, in electrodes for dry batteries and in electroplating and electroforming, in brushes for electric motors and as a neutron moderator in nuclear reactors. Gem quality diamond is used in jewelry, and Industrial diamonds are used in drilling, cutting and polishing tools for machining metals and stone. Carbon black is used as the black pigment in printing ink, artist's oil paint and water colours, carbon paper, automotive finishes, India ink and laser printer toner. It is also used as a filler in rubber products such as tyres and in plastic compounds. Carbon acts as a macronutrient for the body, and is thus greatly required.

Chlorine Dioxide

Chlorine dioxide is a chemical compound. As one of several oxides of chlorine, it is a potent and useful oxidizing agent used in water treatment and in bleaching. It is used in the electronics industry to clean circuit boards, in the oil industry to treat sulfides and to bleach textile and candles. Nowadays chlorine dioxide is used most often to bleach paper. It produces a clearer and stronger fiber than chlorine does. Chlorine dioxide has the advantage that it produces less harmful byproducts than chlorine. It can be used as oxidizer or disinfectant. It is a very strong oxidizer and it effectively kills pathogenic microorganisms such as fungi, bacteria and viruses. It also prevents and removes bio film. As a disinfectant and pesticide it is mainly used in liquid form. It can also be used against anthrax, because it is effective against spore-forming bacteria. Chlorine dioxide gas is used to sterilize medical and laboratory equipment, surfaces, rooms and tools.

Copper

Copper is a ductile metal, with very high thermal and electrical conductivity. It is used as a conductor of heat and electricity, a building material, and a constituent of various metal alloys. Copper compounds are commonly encountered as copper(II) salts, which often impart blue or green colors to minerals such as turquoise and have been widely used historically as pigments. Architectural structures built with copper corrode to give green verdigris. Decorative art prominently features copper, both by itself and as part of pigments. Copper(II) ions are water-soluble, where they function at low concentration as bacteriostatic substances, fungicides, and wood preservatives. In sufficient amounts, they are poisonous to higher organisms; at lower concentrations it is an essential trace nutrient to all higher plant and animal life. The main areas where copper is found in animals are tissues, liver, muscle and bone.
