  • 1. ZincElementProject Zak Konys
  • 2. What does the elements name mean?• It comes from the German name for the element, Zink.• The original meaning is unknown.• Bears a resemblance to German word Zinn meaning tin and Zinke meaning spike or fork.
  • 3. Where was it discovered?• Ancient texts from India and Chinamake reference to Zinc products.• It is thought that the Chineseproduced the first purified zincaround 1000A.D.
  • 4. Who discovered Zinc? • The Swiss alchemist Paracelsus--who was born with the much-lengthier name of Theophrastus Philippus Aureolus Bombastus von Hohenheim. • He first described zinc as a metal in the fifteenth century, and he is often credited with its identification as an element.
  • 5. Properties Zinc exists as a solid at room temp, it’s neither ductile nor malleable (at room temp).• Ductile means capable of being drawn into thin wires.• Malleable means capable of being hammered into thin sheets.
  • 6. PropertiesWhat is the color?Zinc is a bluish-white metal with a shiny surface(notice the background).
  • 7. PropertiesMelting and boiling points• 787.1 F (419.5 C)• 1,665 F (907 C)Density• 7.14 grams per cubiccentimeter
  • 8. Major IsotopesFive naturally occurring isotopes of zinc are: 1. zinc-64 2. zinc-66 3. zinc-67 4. zinc-68 5. zinc-70 (naturally radioactive).Twenty-four artificial radioactive isotopes of zincare also know.
  • 9. Major IsotopesZinc-65 (artificial & radioactive) is used as a tracer to studyphysical and biological events.
  • 10. Availability• Zinc’s abundance in the Earth’s crustis estimated at 0.02%.• Approximately 23rd on the list of theelements in abundance.
  • 11. Where is Zinc found?• As of 2008, the largest producers of zinc ore were China, Australia, Peru, the United States and Canada.• In the united states, zinc was mined in seven states.
  • 12. To get the elementTwo ways to produce zinc. 1. Roasting (heating in air) converts the ore to a compound of zinc and oxygen. 2. Pass an electric current through a compound of zinc. The electric current causes it to break apart producing pure zinc.
  • 13. Cost of ZincCost, pure: $5.30 per 100gCost, bulk: $0.18 per 100g
  • 14. Common uses of ZincThe most important use of zinc todayis in galvanizing (thinly covering) othermetals.Zinc does not corrodeas easily as iron andother metals.
  • 15. Common uses of ZincCommonly used as an AnodeWhen attached to steelZinc will deteriorate,instead of steel, andprotect the steel in asalt water environmentsuch as a bridge orboat.
  • 16. Common Uses of Zinc In humans, zinc deficiencies are serious. It is used to build molecules of DNA.
  • 17. Major compounds containing Zinc and uses.• zinc acetate (Zn(C2H3O2)2): wood preservative; dye for textiles; additive for animal f eed; glazing for ceramics• zinc arsenate (Zn3(AsO4)2): wood preservative; insecticide• zinc borate (ZnB4O7): fireproofing of textiles; prevents the growth of fungus and mild ew• zinc chloride (ZnCl2): solder (for welding metals); fireproofing; food preservative; addi tive in antisepticsand deodorants; treatment of textiles; adhesives; dental cement; pet roleum refining; and embalming and taxidermy products• zinc fluorosilicate (ZnSiF6): mothproofing agent; hardener for concrete.• zinc hydrosulfite (ZnS2O4): bleaching agent for textiles, straw, vegetable oils, and oth er products; brightening agent for paper and beet and cane sugar juice.• zinc oxide (ZnO): used in rubber production; white pigment in paint; prevents growth of molds on paints; manufacturer of glass; photocopy machines; production of many kinds of glass, cera mics, tile, and plastics.• zinc phosphide (Zn3P2): rodenticide (rat killer)• zinc sulfate (ZnSO4): manufacture of rayon; supplement in animal feeds; dyeing of te xtiles; and wood preservative.
  • 18. Fun Fact• A Penny is 97.5% zinc & 2.5% copper plating.
