Silver
Pure silver is nearly white, lustrous, soft, very ductile, malleable, and an excellent conductor of heat and electricity. In many of its properties it resembles copper and gold, the elements above and below it in group Ib of the periodic table. It is not a chemically active metal, being considerably below hydrogen in the electromotive series.
Silver melts at 961 degrees C and boils at 2193 degrees C. At 20 degrees C, it has a density of about 10.49 grams per cubic centimeter. Silver reflects 95 percent of the light that strikes it, making it the most lustrous (shiny) of the metals. Silver conducts heat and electric current better than any other metal does. It is second only to gold in ductility (the ability to be drawn out into fine wires) and malleability (the ability to be hammered into various shapes).
Many beautiful objects, including jewelry, fine tableware, religious decorations, coins, and mirrors, are made of silver. Silver also plays an important role in dentistry, medicine, photography, and electronics.
