Mercury is a
chemical element with the symbol
Hg and atomic
number *0, also known as
Hydrargyrum, Hydrargyri. 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, gallium, and rubidium melt just above room
temperature. With a freezing
point of −*8.*3 °C and boiling
point of **6.*3 °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). Mercury
poisoning can also result from exposure to
water-soluble forms of mercury (such as mercuric
chloride or methyl
mercury), inhalation of mercury vapor, or eating
seafood contaminated with mercury.

Physical
properties
Â
A
pound coin (density ~7.6 g/cm3)
floats in mercury due to the combination of the buoyant
force and surface
tension.
Mercury is a heavy, silvery-white metal. As
compared to other metals, it is a poor conductor of heat, but a
fair conductor of electricity. A complete explanation of this
delves deep into the realm of quantum
physics, but it can be summarized as follows:
mercury has a unique electronic configuration where electrons
fill up all the available 1s, 2s, 2p, 3s, 3p, 3d, 4s, 4p, 4d, 4f,
5s, 5p, 5d and 6s subshells.
The
stability of the 6s shell is due to the presence of a filled 4f
shell.. The absence of a filled inner f shell is the
reason for the somewhat higher melting temperature of
cadmium and zinc, although both these metals
still melt easily and, in addition, have unusually low boiling
points.
Â
Chemical
properties
Mercury does not react with most
acids, such as dilute sulfuric acid, although
oxidizing acids such as
concentrated sulfuric acid and nitric
acid or aqua
regia dissolve it to give sulfate, nitrate, and chloride salts. Like silver,
mercury reacts with atmospheric hydrogen sulfide. Mercury even
reacts with solid sulfur flakes, which are used in mercury spill
kits to absorb mercury vapors (spill kits also use activated carbon and powdered
zinc).
