  1. Mercury Quick Silver

  2. Mercury got its chemical symbol from the Latin word Hydrargyrum which is a Greek word and means quick silver. Atomic Number: 80 Group: 12 Period: 6 Part of the Transition Metals Name from the Greek god Mercury who was the messenger to the gods and was known for his speed The name

  3. Discovery • Mercury was one of the first elements discovered • It was discovered so long ago that no one is sure who discovered it, where they did, and the exact date • Samples of the element have been found in Egyptian tombs as far back as 1500 B.C. • It was also well know to the ancient Chinese • Ancient Greeks used it as a medicine

  4. Electron Configuration Mercury's configuration:[Xe]4f14,5d10,6s2

  5. Physical Properties • Mercury is a metal that becomes a liquid at room temperature. • It is highly reflective. • Even though Mercury is a liquid it is not wet. It will not soak into a material but slides across it.

  6. Physical Properties • Mercury has a very high density of 13.6 • It is so dense that things like bricks, cannonballs, and lead will float in Mercury • It is 13 ½ times as heavy as the volume of water • Mercury has no taste

  7. Physical Properties • Specific Heat: 0.139J/gK • Melting Point: 234.28K -38.72°C -37.7°F • Boiling Point: 630K 357°C 675°F • Atomic Mass Average: 200.59

  8. Price of Mercury • Mercury is a rare element so the price is fairly high • At www.vhglabs.com a 25ml sample of mercury costs $85.00. Other places will very

  9. Chemical Properties • Mercury is a decent conductor of electricity but is very poor at conducting heat • Rarely found as a pure metal in nature • Metallic Mercury is obtained from heating Cinnabar

  10. Chemical Properties • Has high surface tension • Is able to dissolve other metals to form alloys known as amalgams

  11. Uses of Mercury • Mercury can be used to make thermometers • Also other scientific instruments and barometers • Mercury conducts electricity and is used to make silent, position dependent switches

  12. Uses of Mercury • Its vapor is used in streetlights, fluorescent lamps and advertising signs. • Mercury can form alloys with other metals, such as gold, silver, zinc and cadmium. • A mercury and silver amalgam creates dental fillings • Also paints and batteries

  13. Uses of Mercury • Pesticides - Fungicides and biocides produced before 1994 used mercury toxins to kill fungus, weeds and other pests. Most new pesticides are mercury-free. • Clothing Irons - Some irons have an automatic shut-off switch containing mercury. Irons with mercury-free automatic shut-off switches are available. • Athletic Shoes - Some athletic shoes with flashing lights in the soles contain mercury. Some states have banned the sale of these shoes. Newer shoes are mercury-free. • Blood Pressure Gauges - Home blood pressure gauges contain almost 1.5 pounds of mercury. An aneroid blood-pressure unit is a mercury-free option.

  14. Dangers of Mercury • Mercury, once used extensively in the hat making process, caused a brain illness in many hatters. • Hat makers, exposed to large amounts of vaporized mercury, began to experience its effects on their nervous systems. Doctors even recorded seeing "holes the size of quarters" inside some hatters' brains.

  15. Dangers of Mercury • Methyl mercury is a lethal pollutant found in rivers and lakes • Mercury is very toxic and must be handled with extreme care • Mercury poisoning could come from eating contaminated fish

  16. Dangers of Mercury • Some symptoms of mercury poisoning are Irritability, Nervousness, Fits of Anger, Memory Loss, Lack of Attention, Depression, Low Self Confidence, Anxiety, Drowsiness, Shyness/timidity, Decline of Intellect, Insomnia, Low Self Control

  17. Dangers of Mercury • In several areas of the United States, concentrations of mercury in fish and wildlife are high enough to be a risk to wildlife.
