Dental amalgam is a mixture of liquid (elemental) mercury and a powdered alloy made up of silver, tin and copper. Elemental mercury makes up about 50% of dental amalgam by weight and reacts with ...
Lead. Lead is a heavy metal that is denser than most common materials. Lead is soft and malleable, and has a relatively low melting point. Lead is widely used as a gamma shield. Major advantage of lead shield is in its compactness due to its higher density. Lead has the highest atomic number of any stable element and concludes three major decay ...
Mercury is a silvery-white liquid post-transition metal. The reason for mercury being a liquid is complex. It is heavy; a chunk of iron can float on mercury. Compared to other metals, it does not conduct heat well. …

The main factors for the existence of mercury as a liquid are: Atomic size contraction. Weak intramolecular bonds among mercuric atoms. Electronic configuration. Contraction of atomic size is a phenomenon usually seen in periods in the periodic table.
While liquid mercury itself it toxic, the main danger is the vapor it releases as it evaporates. As with any hazardous waste, it's always a good idea to check with your local health department,...
There are a couple of reasons why Mercury is a liquid at STP, I will go through each of them with an explanation that won't be too complex for your understanding. First of all understanding why most metals are metallic is a good place to start. This happens because of the sharing of valence electrons.

Elemental mercury (liquid mercury, quicksilver): You'll find elemental mercury in glass thermometers, electrical switches, fluorescent lightbulbs and dental fillings. Inorganic …
Laptop computers, LCD TVs and compact fluorescent light bulbs are all safe as long as they're intact, but if they crack or shatter, they can release toxic mercury vapor. See the graphic above for ...
The equilibrium evaporation of mercury from dilute solutions in liquid lead–bismuth eutectic (LBE) was studied in argon atmosphere. Mercury present as impurity in LBE was evaporated and detected by atomic fluorescence spectroscopy. A method which could accurately simulate the experimental data was developed.
Mercury has got to be one of the most fascinating elements around. In looking at the bubbles of bright silver sitting on a flat surface, it is easy to see why mercury is also called "quicksilver." Mercury is the only metal that exists in liquid form. It may act somewhat like water, but it is nothing at all like water, especially in the potential harmful …
Mercury, or 'quicksilver' as it is otherwise known, is a dense, toxic metal element that exists in liquid form at room temperature. Produced and studied for millennia, mercury's use has steadily declined since the …
It is named after the planet Mercury and often referred to as "quicksilver" due to its appearance as a silvery liquid. Mercury has low melting and boiling points. It is a poor conductor of heat, but a fair conductor of electricity. Mercury is found both as a free element and in cinnabar, corderoite, and livingstonite ores. Recent Research
Mercury has fascinated people for millennia, as a heavy liquid metal. However, because of its toxicity, many uses of mercury are being phased out or are under review. It is now mainly used in the chemical industry as catalysts. It …
A violent exothermic reaction, possibly an explosion, occurs when mercury comes in contact with chlorine dioxide, lithium, or rubidium. It also reacts with acetylenic compounds, ammonia, azides, boron diiodophosphide, ethylene oxide, methyl azide, methylsilane, oxygen, oxidants, and tetracarbonylnickel.
The risk from elemental mercury is ingestion and inhalation. Ingestion is a "normal" risk, similar to that of other toxic chemicals and cleaners, and it should not be eaten. The vapor pressure of mercury is …
Mercury is a metal that can turn to vapor at room temperatures. The lungs can easily absorb this vapor, and once mercury is in the body, it can pass through cell membranes and the blood-brain...
Mercury is silvery white, slowly tarnishes in moist air, and freezes into a soft solid like tin or lead at −38.83 °C (−37.89 °F). It boils …

Alchemists were convinced that mercury transcended both the solid and liquid states, both earth and heaven, both life and death. Mercury is one of the seven metals of alchemy (gold, silver, mercury, copper, lead, iron & tin). The symbol for mercury could also be used to represent the planet of the same name in astrology.
Mercury is used to bind the alloy particles together into a strong, durable, and solid filling. Mercury's unique properties (it is a liquid at room temperature that bonds well with the alloy...
Nickel alloys can also suffer from liquid metal embrittlement by zinc or mercury, but to a lesser degree than carbon and stainless steels (18Cr-8Ni type). The severity of liquid metal embrittlement depends on the magnitude of local stresses and the prevailing temperature. A relative ranking order from the most to least susceptible nickel alloys ...

The inhalation of mercury vapour can produce harmful effects on the nervous, digestive and immune systems, lungs and kidneys, and may be fatal. The inorganic salts of mercury are corrosive to the skin, eyes and gastrointestinal tract, and may induce kidney toxicity if ingested.
Figure 10.4. 1: Evaporation. Some particles of a liquid have enough energy to escape the liquid phase to become a vapor. If the available volume is large enough, eventually all the liquid will become vapor. But if the available volume is not enough, eventually some of the vapor particles will reenter the liquid phase (Figure 10.4. 2 …
