  • HistoryLatin Name Aurum, originally called shining dawn. No one can really say who discovered Gold because gold has been around for thousands of years B.C. and some say even early as prehistoric times Egypt and especially Nubia had the resources to make them major gold-producing areas for much of history.

  • Description: Soft bright yellow transition metal.Boiling Point: 3080K, 2807C, 5085FMelting Point: 1337.73K, 1064.58C, 1948.24FDensity:19.32g/cc @ 300KConductivity: Electrical: 0.452 106/cm Thermal: 3.17 W/cmKElectron Configuration: 1s2 2s2p6 3s2p6d10 4s2p6d10f14 5s2p6d10 6s1Electron Dot Formula: Au.

  • InformationGold - AuType of Ion: Cat ionOxidation States: 3 , 1Valence Electron: 1Atomic Number:79 Group: 11 Period: 6Transition MetalIsotopes: 18

  • OccurrencesHeath BenefitsNative gold is also found in the form of free flakes, grains or larger nuggets that have been eroded from rocks and end up in alluvial deposits (called placer deposits)Gold Salt have anti-inflammatory properties and are used in the treatment of arthritis and other similar conditionsInject able Gold has been proven to help to reduce the pain and swelling of rheumatoid arthritis and tuberculosis.Gold Alloys are use in dentistry in tooth restoration(crowns & permanent bridges)

  • ReactionsProblemsPure metallic (elemental) gold is non-toxic and non-irritating when ingestedGold is chemically unreactive and exists in nature in its pure form.

    Gold Salt are toxic to the liver and kidneysRare poisoning from Potassium gold cyanideGold contact allergies have affected mostly women but is relatively non-potent when compared to Nickel

  • PriceThere is really no set price, the price of gold fluctuates and continues to changeIt depends on the karat which is how pure the gold is 24 being the finenessAlso it is weighed by 1 troy ounce = 31.1 grams worth $1340.60

  • Uses Of Gold Jewelry Gold Flakes (food) Thread Coloring Agent (Cranberry Glass) Reflective Layer On Cds Protective Coating (Satellites) Automobiles (Heating Dissipation) Gold Toners (Photography)

  • Symbolism of GoldSymbolismRepresentsGold has been highly valued in many societies throughout the agesEx: Golden Medals awarded in athletic competitions and trophies (Olympic Games, Nobel Prize, & Gold Globe Awards)PowerStrengthWealth Warmth HappinessLoveHopeOptimism
