Mercury | Chemical elements

Mercury has been known since ancient times. Its name derives from the name of the planet Mercury and its symbol drives from the Latin word "hydrargyrum" which means "liquid silver". Mercury’s melting point is at -38.87 °C (234.28 K, -37.966 °F) and its boiling point is at 356.58 °C (629.73 K, 673.844 °F).

Top 15 interesting facts about Mercury

  1. Mercury is also known as “quick silver”.
  2. Mercury has a silvery-white color.
  3. Mercury is a heavy metal.
  4. Mercury is a liquid at standard temperature; although it is a metal (it is the only metal that is a liquid in normal conditions of temperature and pressure).
  5. Although mercury is a liquid, a coin floats if placed on mercury.
  6. Mercury reacts with a few of the concentrated acids and with aqua regia.
  7. Mercury dissolves gold and silver and readily reacts with aluminum.
  8. Mercury has seven stable isotopes: 196-Hg, 198-Hg, 199-Hg, 200-Hg, 201-Hg, 202-Hg (the most abundant), and 204-Hg.
  9. Mercury is a very rare element on Earth’s crust.
  10. Cinnabar is the most common ore of mercury.
