Mercury (Hg) is a chemical element with the atomic number 80 and is a transition metal. This element is considered a heavy metal, but can also exist in a liquids form at room temperature and pressure. It found in the crust of the Earth but its natural state is found as cinnabar or mercuric sulfide. Mercury has many uses that are found in medications and as vermilion. It is also used in thermometer, barometers, manometers, and scientific instruments, however recently due to the toxicity of mercury these instruments have been replaced with alcohol-filled or digital instruments.
