1.Mercury is the only one liquid metal at room temperature which is used in instruments for measuring blood pressure.
2. Element mercury is the element in pure, ' uncombined' form. But rarely found in nature. Mercury compounds are found in nature, in the form of oxide , sulphide ore etc.
3. Mercury being less reactive, it is extracted from its ore cinna bar ( mercury sulphide)
steps involved in extraction:
a). Mercury ore is roasted to get mercury oxide.
b) Mercury oxide is heated at high temperature ( 300degrees Celsius) to get metal Mercury

mercury is the metal .
It can extracted by heating the ore (HgS).By heating it will metallic oxide (MgO).Further the metallic oxide is heated to give mercury.

The reaction involved
HgS +3O^2=2HgO +2SO

further heating
2HgO =(heat)2Hg +O^2
