<P> Besides its widespread monetary and symbolic functions, gold has many practical uses in dentistry, electronics, and other fields . Its high malleability, ductility, resistance to corrosion and most other chemical reactions, and conductivity of electricity led to many uses of gold, including electric wiring, colored - glass production and even gold leaf eating . </P> <P> It has been claimed that most of the Earth's gold lies at its core, the metal's high density having made it sink there in the planet's youth . Virtually all of the gold that mankind has discovered is considered to have been deposited later by meteorites which contained the element . This supposedly explains why, in prehistory, gold appeared as nuggets on the earth's surface . </P> <P> 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 rubidium melt 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 . </P> <P> 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 or methylmercury), inhalation of mercury vapor, or eating seafood contaminated with mercury . </P>
