Salient Features of Mercury Mercury is a heavy and silvery-white metal. Mercury usually available inin liquidliquid state; inin normal condition, itit isis only thethe fewfew metallic element that remains in liquid state at room temperature. Mercury is the poor conductor of heat, but it is a good conductor of the electricity.. The freezing point of mercury is −38.830C and the boiling point is 356.730C. Mercury poisoning caused because of thethe ingestingingesting any formform of mercury.. ItIt isis also caused by inhalation of mercury vapor.. https://www.tutorialspoint.com/chemistry_part2/chemistry_mercury.htm 1/3 1/24/2021 Chemistry - Mercury - Tutorialspoint Mercury dissolves many metals including gold and silver to form amalgams. Occurrence of Mercury Mercury is one of the rarest element in the earth’s crust. The richest mercury ores carry about 2.5 percent mercury (in terms of mass). Mercury isis foundfound either as a native (natural) element) or inin corderoite, cinnabar,, livingstonite,livingstonite, etc.etc. minerals.minerals. Mercury iis foundfound thethe region of young mountain belt; thethe belt thatthat keep forcingforcing thethe denser rocks to the crust of the earth. For example, volcanic region or even hot spring regions. Alloys of Mercury Amalgam is the major alloy of mercury..
