Hg - Mercury

Famous for its toxic properties and it's physical state, mercury is a liquid heavy metal. It is used in the laboratory thermometers, manometers and barometers encountered in all of our chemistry classes. Analytical chemistry students analyse the trace amounts of mercury vapor in the air.
