1 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

3 Mercury was one of the first elements discovered 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 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. 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 It was also well know to the ancient Chinese Ancient Greeks used it as a medicine Ancient Greeks used it as a medicine

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

5 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 Mercury has a very high density of 13.6 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 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 It is 13 ½ times as heavy as the volume of water Mercury has no taste Mercury has no taste

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

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

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

12 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 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. 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.

14 Mercury, once used extensively in the hat making process, caused a brain illness in many hatters. 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.

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