MERCURY

Mercury
Hunted Facts on mercury
  • Mercury salts are sometimes used in skin lightening creams and as antiseptic creams and ointments.
  • Mercury's harmful effects that may be passed from the mother to the fetus include brain damage, mental retardation, incoordination, blindness, seizures, and inability to speak.
  • Mercury in whole blood or in scalp hair is measured to determine exposure to methylmercury.
  • Mercury was named by the Romans after the fleet-footed messenger of the gods because it seemed to move more quickly than any other planet.
  • Mercury's rolling, dust-covered hills have been eroded from the constant bombardment of meteorites.
  • Although Mercury is not tidally locked to the Sun, its rotational period is tidally coupled to its orbital period.
  • Mercury is the smallest of the inner, rocky planets (Mars, Earth, and Venus) and the closest to the Sun.
  • This hypothesis also predicts that Mercury should have higher concentrations of elements that have very high boiling points (called refractory elements), such as calcium and aluminum, and not much of the elements that boil at low temperatures (called volatile elements), such as sodium and potassium.
  • This indicates that the surface in this region of Mercury is underlain by a chemically distinctive layer at depth.
  • Mercury is not well absorbed across the skin so skin contact is not likely to cause mercury poisoning, especially with a brief one-time exposure.
  • Inorganic mercury compounds are known as "mercuric salts." Some of the mercuric salts include: mercuric chloride, mercuric iodide, mercuric nitrate, mercuric sulfide, yellow mercuric oxide, red mercuric oxide, ammoniated mercury, mercurous chloride and mercurous acetate.
  • A spill of a large amount of mercury (more than the amount of mercury in a household fever thermometer) can be dangerous to all members of the household including pets because of the mercury vapors in the air of the house.
  • Mercury is the only body in the solar system known to have an orbital/rotational resonance with a ratio other than 1:1 (though many have no resonances at all).
  • Mercury's interior is dominated by a large iron core whose radius is 1800 to 1900 km.
  • Mercury is often visible with binoculars or even the unaided eye, but it is always very near the Sun and difficult to see in the twilight sky.
