n.
a silvery metallic element that is liquid at room temperature. Its toxicity has caused a decline in the use of its compounds in medicine during this century; mercurial compounds were formerly used in the treatment of syphilis and as purgatives, teething pastes and powders, fungicides, and antiparasitic agents. Mercury is widely used in dentistry as a component of amalgam fillings; when the mercury is combined with the filling alloy, it is nontoxic. Symbol: Hg. See also mercurialism, pink disease.

mer·cu·ry (Hg) (murґkūr-e) a metallic element, liquid at ordinary temperatures; atomic number, 80; atomic weight 200.59, specific gravity 13.546. It is insoluble in ordinary solvents, partially soluble in boiling hydrochloric acid, and soluble in nitric acid. It forms two sets of compounds: mercurous, in which a single atom of mercury combines with a monovalent radical, and mercuric, in which a single atom of mercury combines with a bivalent radical. The mercuric salts are more soluble and irritant than the mercurous ones. Mercury and its salts have been used medicinally, but because of the risk of mercury poisoning (see under poisoning) their use has diminished.
