This is a perfect sample for many science lab experiments and collections. •Great chemistry gift •Amazing science gift • Sweet Stocking stuffer, Christmas gift The Facts •Copper, Silver and Gold are apart of Group 11 in the periodic table. •Group 11 is also known as the coinage metals due to the metals all being used in currency. •These metals were most likely the first three elements ever discovered and have been known about since prehistoric times. •Copper, silver, and gold all occur naturally in elemental form. •Because they all occur in metallic form in nature and no extraction metallurgy is necessary to produce them. •All Group 11 elements are relatively inert, corrosion-resistant metals. Copper and gold are colored. •Copper, although toxic in excessive amounts, is essential for life. Copper is shown to have antimicrobial properties which make it useful for hospital doorknobs to keep diseases from being spread. Eating food in copper containers is known to increase the risk of copper toxicity. •Elemental gold and silver have no known toxic effects or biological use, although gold salts can be toxic to liver and kidney tissue. Like copper, silver also has antimicrobial properties. The prolonged use of preparations containing gold or silver can also lead to the accumulation of these metals in body tissue; the results are the irreversible but apparently harmless pigmentation conditions known as chrysiasis and argyria respectively. This is high quality yet cheap affordable Copper, Silver and gold metal. •This sample is great for fun science experiments and Collections   Shipping I offer free shipping to the USA; international is additional.
