Mercury has a high density and surface tension and can easily break up into small droplets. Mercury is also called as quicksilver or hydrargyrum. Bromine is a non-metal. At the other hand, no mercury is present, so no current will pass. 2.702. It does not react with oxygen in the air. At a temperature of-38.85 °C (– 37.93 °F), mercury can be frozen (changed into a solid). There is in fact only another liquid element, bromine. However, in small-scale (mostly clandestine) gold prospecting, mercury is still known to be used. Mercuric sulphate is used as a catalyst in organic chemistry. Required fields are marked *, Based on the aforesaid mean value of the density at 20, C and using the Beattie formula giving the density of mercury have been generated. 2. Mercury's chemical symbol comes from the Greek word hydrargyrum, which means "liquid silver." Surface tension is a property of liquids that makes them act like they are covered with skin. Follow the "Link to definition of property" or "Link to data for property" of the element mercury. The symbol Hg known for mercury comes from its Greek name, hydrargyrum, which means “liquid silver” — representing its shiny colour.
