Do you remember the copper colored crayon in the box of 96 (or was it 100? You know the really big box with the sharpener on the back)? I loved the way it went onto the paper really smoothly. I also liked the metallic sheen it had.<\/p>\n

Definition<\/a>: “Copper<\/b> is a chemical element<\/a> with symbol Cu<\/b> (from Latin<\/a>: cuprum<\/i><\/span>) and atomic number<\/a> 29. It is a ductile<\/a> metal with very high thermal<\/a> and electrical conductivity<\/a>. Pure copper is soft and malleable; a freshly exposed surface has a reddish-orange color. It is used as a conductor of heat and electricity, a building material, and a constituent of various metal alloys<\/a>.<\/p>\n

The metal and its alloys<\/a> have been used for thousands of years. In the Roman era, copper was principally mined on Cyprus<\/a>, hence the origin of the name of the metal as ?yprium<\/i> (metal of Cyprus), later shortened to ?uprum<\/i>. Its compounds are commonly encountered as copper(II) salts, which often impart blue or green colors to minerals such as azurite<\/a> and turquoise<\/a> and have been widely used historically as pigments. Architectural structures built with copper corrode to give green verdigris<\/a> (or patina<\/a>). Decorative art<\/a> prominently features copper, both by itself and as part of pigments.<\/p>\n

Copper is essential to all living organisms as a trace dietary mineral<\/a> because it is a key constituent of the respiratory enzyme complex cytochrome c oxidase<\/a>. In molluscs<\/a> and crustacea<\/a> copper is a constituent of the blood pigment hemocyanin<\/a>, which is replaced by the iron-complexed hemoglobin<\/a> in fish and other vertebrates<\/a>. The main areas where copper is found in humans are liver, muscle and bone.[2]<\/a><\/sup> Copper compounds are used as bacteriostatic substances<\/a>, fungicides<\/a>, and wood preservatives.” (Wikipedia)<\/p>\n
