Why is mercury so hard to study?
Mercury is closest to the Sun. It is one of the inferior planets, that is, its orbit (around the Sun) is smaller than Earth's orbit and hence takes much less time to go around the Sun. Mercury takes 88 days to go around the Sun, as compared to the 365 days the Earth takes. Because of these reasons, Mercury is difficult to see.

What happens if mercury touches you?
If you touch it, a small amount may pass through your skin, but not usually enough to harm you. Mercury is most harmful when you breathe in the vapors that are released when a container is open or a spill occurs. Pregnant women, infants and young children are particularly sensitive to the harmful effects of mercury.
What happens if you boil mercury?
When heated to near its boiling point (346.72 deg C/675 deg F), mercury oxidizes in air, and mercuric oxide is formed. At 500 deg C, mercuric oxide decomposes into mercury and oxygen, a phenomenon that led to the discovery of oxygen by Joseph Priestley and Karl Scheele.

What is the old name for mercury?
Quicksilver: is the old name for mercury. Quick is the old word for life, and silver is the metal silver. Mercury or quicksilver is liquid at room temperature and flows readily as if it were alive.
Why is Mercury so dense?
Another consequence of this, is that the Van der Walls radius, which is a effectively the size of the atom, is low, compared with the other atoms around it in the periodic table. This is why it is so dense - more dense than one would expect. On top of this, Mercury has the highest ionisation energy of any other metallic atom. These are both consequences of its 2 6s electrons having a much lower energy than the patterns predict, and that they are therefore closer in to the nucleus than they ought to be.
What is the configuration of a mercury atom?
It's configuration is [Xe] 4f14 5d10 6s2. You can see that all of the orbitals are filled, which tends to make it very stable. But, its behaviour is particularly due to its outermost 6s electrons. These are the electrons which would usually be shared between atoms, and lead to the metallic bonding of a solid. They are also the electrons which would be lost or shared, when making chemical bonds. Mercury atoms are extremely reluctant to do either, and this is because they are particularly tightly bound to the Mercury nucleus. The 6s electrons have a strong probability of having very high velocities, close to the speed of light, and this effectively gives them more mass, so that they tend to spend more time close to the nucleus, than one would expect. This is known as ‘relativistic contraction’. The 4f orbitals also provide very poor screening, just adding to the low, and therefore, more stable energies of the 6s electrons.
Why are electrons considered liquids?
Its all due to its structure and electronic configuration. At the atomic level, yes, electrons do explain why a substance is a liquid as well as its metallic properties. But at the macro level, we cannot simply clump together all metals as being hard rigid solids. 24k Gold is like soft dough, Sodium metal can be cut with a knife.
What does Hg mean in the Greek word for mercury?
The symbol Hg that mercury is known by comes from its Greek name, hydrargyrum, which means "liquid silver" — to reflect its shiny surface. The element is also known as quicksilver for its mobility. Named after the fastest-moving planet in the solar system, mercury has been known to humanity for ages. In fact, evidence of its use has been found in China, India and Egypt, and traces of mercury were found in 3,500-year-old Egyptian tombs.
Why does mercury have a low melting point?
The reason mercury has such a low melting and boiling point is because the structure of it’s valence electron shell doesn’t easily form crystal structures.
When was mercury first used in mining?
Beginning in 1558, with the invention of the patio process to extract silver from ore using mercury, mercury became an essential resource in the economy of Spain and its American colonies. Mercury was used to extract silver from the lucrative mines in New Spain and Peru.
What metals dissolve in mercury?
Mercury dissolves many metals such as gold and silver to form amalgams. Iron is an exception, and iron flasks have traditionally been used to trade mercury. Several other first row transition metals with the exception of manganese, copper and zinc are also resistant in forming amalgams. Other elements that do not readily form amalgams with mercury include platinum. Sodium amalgam is a common reducing agent in organic synthesis, and is also used in high-pressure sodium lamps.
Why is mercury not allowed on airplanes?
For this reason, mercury is not allowed aboard an aircraft under most circumstances because of the risk of it forming an amalgam with exposed aluminium parts in the aircraft. Mercury embrittlement is the most common type of liquid metal embrittlement.

The Latin name "hydrargyrum," from which its chemical symbol Hg comes, means water-silver. English speakers used to call it quicksilver, or living silver. The medieval alchemists felt that mercury must have a mighty mojo, some excess of spirit that could be tamed for their great work of turning base metal into gold .
Where is mercury found?
Deposits of mercury, whether in cinnabar or at hot springs , are usually small and rare. The delicate element doesn't last long in any one place; for the most part, it vaporizes into the air and enters the biosphere. Only a portion of environmental mercury becomes biologically active; the rest just sits there or becomes bound to mineral particles.
Is mercury a volatile element?
Mercury is classified as a volatile element, one that lives mostly in the Earth's crust. Its geochemical cycle starts with volcanic activity as magma invades sedimentary rocks. Mercury vapors and compounds rise toward the surface, condensing in porous rocks mostly as the sulfide HgS, known as cinnabar.
