What are the characteristics of mercury?
Mercury is a chemical element with the symbol Hg and atomic number 80. It is also known as quicksilver or hydrargyrum ( < Greek "hydr-" water and "argyros" silver). A heavy, silvery d-block element, mercury is the only metal that is liquid at standard conditions for temperature and pressure; the only other element that is liquid under these conditions is bromine, though metals such as caesium, francium, gallium, and rubidiummelt just above room temperature. With a freezing point of −38.83 °C and boiling point of 356.73 °C, mercury has one of the narrowest ranges of its liquid state of any metal.
Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide). The red pigment vermilion is mostly obtained by reduction from cinnabar. Cinnabar is highly toxic by ingestion or inhalation of the dust. Mercury poisoning can also result from exposure to water-soluble forms of mercury (such as mercuric chloride ormethylmercury), inhalation of mercury vapor, or eating seafood contaminated with mercury.
Mercury is used in thermometers, barometers, manometers, sphygmomanometers, float valves, mercury switches, and other devices though concerns about the element's toxicity have led to mercury thermometers and sphygmomanometers being largely phased out in clinical environments in favor of alcohol-filled, galinstan-filled, digital, or thermistor-based instruments. It remains in use in scientific research applications and in amalgam material for dental restoration. It is used in lighting: electricity passed through mercury vapor in a phosphor tube produces short-wave ultraviolet light which then causes the phosphor tofluoresce, making visible light.
Mercury glass is a special method in which glass is blown and then inlaid with silver although mercury was not always used to do this. The surfaces of the glass are generally very reflective like a mirror and come in a variety of colors. The surface of the glass could even be described as looking metallic.
According to the NASA website, the magnetic field on Mercury has the following characteristics: Dipole field strength: 0.0033 gauss-Rh3 Dipole tilt to rotational axis: 169 degrees Longitude of tilt: 285 degrees (from Mercury I flyby) 115 degrees (from Mercury III flyby) (whereby Rh denotes Mercurian radii, 2,439 km)
Mercury is the innermost and smallest planet in the Solar System. It's orbit has the highest eccentricity. It has the smallest axial tilt. You can only view it in the morning or evening twilight. It has a large iron core, which generates a magnetic field about 1% as strong as that of the Earth. Because of this iron core, Mercury is an exceptionally dense planet.
Mariner 10 and MESSENGER have been the only probes to investigate Mercury. mariner 10 was launched 21.45 PST on November 2, 1973. It observed the atmosphere, surface, and physical characteristics of Mercury and Venus. MESSENGER was launched on August 3, 2004. It went into orbit around Mercury, it collected enough data to produce 95% of it's surface.
Does Mercury have any unique characteristics like the Greenhouse effect or something that makes the it unique or unusual or different from the others?

The 3 characteristics of a nonmetal's is that they don't conduct heat very well, they are very hard and brittle, can be solids liquids and gasses at room temp where as metals are always solid apart from mercury and they don't conduct electricity, there is 1 exception which is carbon which does conduct electricity but is a metal.
the softer metals such as sodium, copper, lead, silver, mercury and tin are the better conductors of both heat and electricity. However, many of these, such as sodium, mercury and tin, are not used for applications requiring conducting properties due to other unfavorable characteristics such as toxicity or strong reactivity with surroundings.
The lines are from Mercury because Mercury has lines which are from Mercury which has lines on it because it is Mercury. The lines are Mercury lines because it is Mercury, and since it is Mercury, it has lines from Mercury because it is Mercury totally. So, Mercury has lines from Mercury since being Mercury from Mercury lines. WHAT!

Here are a few main unique characteristics of Mars that separate it from the other planets in our Solar System: • It has two natural satellites. Mercury, Venus, and the Earth each have less than two, and Jupiter, Saturn, Uranus, and Neptune each have much more than two. • It has the largest volcano in our Solar System, Olympus Mons. • It has the largest canyon in our Solar System, Valles Marineris. • It is…
