  1. Mercury (Hg) By Noble Carpenter

  2. Who discovered Mercury? • Discovered by ancient Chinese, Egyptians, Hindus, and Romans • It was found in the Egyptian tombs • It is named after the the Roman God who was a swift messenger

  3. Mercury’s Characteristics • It is a a very heavy liquid • Three types of mercury: elemental, inorganic, and organic mercury • All types are toxic • Silver and white • Found at trace levels in many minerals • Greater concentrations in fossil fuels • Three valence states: elemental (Hg0), monovalent-mercurous (Hg1+), and the divalent mercuric (Hg2+) • Slightly water-soluble • Vapors of elemental mercury can occur at room temperature • Inorganic mercury compounds contain ionic mercury usually in a salt formation

  4. Sources of the Element Mercury • Naturally occurring element normally found in small amounts in rocks, soils, and the oceans • Never breaks down into a less dangerous form • Some natural sources of mercury but humans are responsible for nearly two-thirds of the mercury currently circulating in our environment • Methylmercury [CH3Hg] is the most toxic form • Affects the immune system, alters genetic and enzyme systems, and damages the nervous system (coordination and the senses of touch taste, and sight)

  5. Uses of Mercury • Mercury is found in light switches because conducts electricity • Mercury is found in most paints because gives the paint color • Mercury is found in thermometers and when above -38.8 degrees Celsius • It is used in thermometers so that it expands, telling the temperature • Mercury is found in remote batteries and is used to store the energy in the battery • Used in engineering and factories

  6. Mercury’s Bohr Diagram • It has 80protons and electrons • It has 121 neutrons • The Atomic Mass of Mercury is 200.59

  7. Pictures of Mercury Liquid form of Mercury Thermometer with Mercury Things containing Mercury
