1 5E(1,14,17,18)

2 Copper (Symbol Cu) A ductile, malleable, reddish-brown metallic element that is an excellent conductor of heat and electricity atomic number 29 atomic weight melting point 1,083°C boiling point 2,595°C

3 Major applications of copper electrical wires (60%) roofing and plumbing (20%) industrial machinery (15%) make an alloy (5%) *Example of alloies: brass and bronze bronze brass

4 Everyday uses of copper doorknobs and other fixtures in the house cooking utensils copper bath tubs copper counters decorative art an essential nutrient to all higher plants and animal life

5 Copper in alloys the most important constituents of carat silver and gold alloys and carat solders used in the jewelry industry, modifying the color, hardness and melting point of the resulting alloys e.g. Brass(alloy of copper and zinc and bronze) e.g.cupronickel(alloy of copper and nickel)

6 Industrial Uses of Copper Watt's steam engine firebox wood preservative coins plumbing, roofing and cladding helping in providing hygienic surfaces

7 Electrical uses of copper transformers motors generators wiring and contacts for PC, TV, mobile phones

8 Transportation uses of copper building of trams, lorries, cars, trains electric supper trams overhead contact wires

9 Special things about copper copper deficiency in the human body can lead to gray hair, skin wrinkles, crow's feet, varicose veins and saggy skin copper jewelry has been in vogue since many centuries copper uses also include medicinal remedy for various ailments

10 Other uses used as a wood preservative used in a museum materials testing: (Oddy test) -used to detect chlorides, oxides, and sulphur compounds used to create antimicrobial protective fabrics(e.g.ceramic glazes, stained glass and musical instruments) as a base for other metals(e.g. nickel)
