This chemical element is among the oldest known ones and the longest used by humanity. It is a shiny liquid metal, with the name given after the planet Mercury. In our body, we have micro amounts of mercury, and in excessive amounts this element is toxic to humans and animals. It is not easy to find this element uncombined, but it can be extracted from ores like mercury sulfides which are in plenty in China. Mercury is mostly used in its compounds and alloys with other metals like tin, silver, or gold, used for amalgams with such applications as dental fillings, etc. Mercury and its compounds are used for producing rectifiers, electrical equipment, fluorescent lamps, thermometers, barometers, batteries, some medical treatments, etc.
