Well, if you found a way to ingest it without it coming contact with oxygen, you would die due to explosions. Mercury is definitely a good candidate for toxicity. Remember the Mad Hatter? Hatters went mad from the mercury that they used to cure the felt used to make hats! \n\nMercury is a metalloid that is liquid at room temperature (the only other liquid metal at room temperature is bromine). \n\nMercury: symbol Hg; atomic # 80; atomic mass 200.59; \n\nMercury is extremely rare naturally and is usually obtained by doing something to cinnabar. \n\nAnything else? I don't know, but I'm sure wikipedia has a lot of info on mercury.

Actually, you can use many other materials for a thermometer, not just mercury.   Mercury is nice because it has properties that make it easier to build a more practical thermometer than the others.   For one it is liquid at room temperature.    Mercury would not be a good material for a thermometer below it's freezing point (see www.webelements.com for details)    Assuming we want thermometer for measuring temperature variations around room temperature, then the other properties of mercury, that is, its temperature expansion coefficient and pressure compressibility, are just right so it will expand predictably over the approximately 1 or 2 inch range that it in your thermometer.    \n\nHope that wasn't too long winded.

Mostly hydrogen. There is a little bit of helium and heavier elements in there as well.

Mercury(II) oxide decomposes into its elements when heated.\nThere is no way that you would know this unless you had been taught about thermal decomposition. So all you need to worry about is the correct formula of oxygen gas.\n\nTherefore 2HgO --> 2Hg + O2.

Ethanol. with a coloring in it. Red or Blue usually.\n Hey all of you who are saying "mercury".....If you have a mercury thermometer in your home dispose of it quickly and safely! Even a small Mercury spill must be reported quickly as it can poison hundreds of people! It is considered as hazmat situation!! Contact with even tiny amounts of mercury can cause brain damage, birth defects and death. Mercury has no place in the home.

The planet Mercury was named after a roman "god", he was the messenger of the gods. He's the one with wings on his feet and a helmet with wings. The element mercury was named after this planet. Mercury was known for speed and mobility, which is probably why the planet (which is the fastest around the sun) and the element (which has mobility compared to other elements) are named after him.

The simple answer:\nMercury is absorbed into the tissue of the organism where where it cannot be purged quickly and therefore it accumulates. \n\nA more complicated answer:\nAbsorbed mercury, causes the solution of mercury compounds in sodium chloride facilitating their transformation into complex compounds, shloroalbuminates. The latter are large complex molecules, in which mercury preserves its ionized state and carries a positive electrical charge.

Cinnabar which is Mercury Sulfide (although there are about 25 mercury ores known, this is the one most often used commercially). \n\nHgS. Mercuric (mercury) sulphide. Most mercury mined comes from cinnabar ore (rock containing cinnabar mineralization). The color of cinnabar ranges from cinnamon to brick and scarlet red, which explains its historic use as a pigment, mainly in paints but also as a traditional colorant for foods. \n\nMecury ores in Spain contain 12-14% mercury although in most places the ore is typically about 1%. Some samples contain up to 86%! Cinnabar is also mined in Texas (in fact, Indians used it for red paint), Peru, Slovenia -- mercury is found everywhere. \n\nMercury is easy to recover from Cinnabar. Ore is crushed to typically 1" to 2" in size then sent to a kiln. Simply heating the ore in a kiln to 1,100 Deg. F, all of the mercury will vaporize into the kiln (mercury vaporizes at 675 deg F). The kiln vapors then must be condensed, by cooling, to recover the mercury, which becomes liquid at temperatures below 675 deg F and freezes solid at 2.8 Deg. F. Some free mercury in the ore can be recovered on Deister wet gravity concentration tables, also. \n\nTypical minerals found with cinnabar include silica, calcite, pyrite, marcasite and bitumen. These minerals often comprise the waste material in a mercury mine.

I'll describe them by each element:\nLi:used primarily in heat-transfer applications, batteries (mainly cell phone and camera batteries), household appliances such as toasters and microwaves, and in high performance alloys such as those used for aircraft construction.\n\nNa:used to refine some reactive metals, such as zirconium and potassium, from their compounds. This alkali metal as the Na+ ion is vital to animal life. Other uses: In certain alloys to improve their structure. In soap, in combination with fatty acids. Sodium soaps are harder (higher melting) soaps than potassium soaps. \nTo descale metal (make its surface smooth). \nTo purify molten metals. In sodium vapor lamps, an efficient means of producing light from electricity \n\nK: It is primarily used in fertilizer as either the chloride, sulfate or carbonate - not as the oxide. \nPotassium hydroxide is an important industrial chemical used as a strong base. \nPotassium nitrate is used in gunpowder (black powder). An older term for KNO3 is saltpeter. \nPotassium carbonate, known as potash, is used in glass manufacturing. \nGlass treated with liquid potassium is much stronger than regular glass. \nNaK, pronounced "nack", an alloy of sodium and potassium which is liquid at room temperature, is used as a heat-transfer medium. It can also be used as a desiccant for producing dry and air-free solvents. \nPotassium is an essential component needed in plant growth and is found in most soil types. \nIn animal cells potassium ions are vital to keeping cells alive \nPotassium chloride is used as a substitute for table salt and is also used to stop the heart, e.g. in cardiac surgery and in executions by lethal injection in solution. \nThe superoxide KO2 is used as a portable source of oxygen and as a carbon dioxide absorber. It is useful in portable respiration systems. \n\nRb: A working fluid in vapor turbines. \nA getter in vacuum tubes. \nA photocell component. \nThe resonant element in atomic clocks.

mercury expands when heated.  not very much though, that's why it's in such a thin tube-- so the results are exaggerated, more visible, and more easily measured

Like the Earth, Mercury has an iron core. But Mercury's core occupies proportionately more (3/4) of the planet's diameter than Earth's does (about half). You can think of Mercury as a metal ball the size of the Moon surrounded by about 700 kilometers (430 miles) of rocky crust. The large relative size of Mercury's core makes it the most iron-rich planet in the solar system, with iron accounting for 65-70% of the planet's mass. Mercury's abundance of iron resulted from its position near the Sun. When the planets were forming out of the same cloud of gas and dust as the Sun, the temperatures in the warm inner regions of the primordial solar nebula were so high that iron-rich minerals were just about the only ones that could condense into solids. Farther away from the Sun, other minerals could also condense. Thus the iron content of the rocky planets in the solar system decreases with increasing distance from the Sun.\n\nMercury's iron core may also be responsible for one of the most surprising findings from Mariner 10 — the planet's weak magnetic field, 100 times weaker than Earth's. Astronomers and geologists are still trying to figure out what causes Mercury's field. In the case of the Earth, rapid rotation of its molten iron core generates electrical currents which produce the Earth's magnetic field. But Mercury is so small, astronomers had assumed its core had cooled and solidified. Plus, it rotates too slowly to generate a magnetic field the way the Earth does. Or so they thought. Perhaps Mercury's core is still partially liquid, or perhaps the magnetic field is "left over'' from an earlier time when the iron core was molten. Astronomers continue to work on this puzzle.

Some mercury compounds take the form of crystals.\n\nInorganic mercury compounds take the form of mercury salts and are generally white powder or crystals, with the exception of mercuric sulfide (cinnabar) which is red. Inorganic mercury compounds have been included in products such as fungicides, antiseptics or disinfectants. Some skin lightening and freckle creams, as well as some traditional medicines, can contain mercury compounds.
