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 is essential for life Elemental gold and silver have no known biological use, although gold salts can be to liver and kidney tissue. Like copper, silver. 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
