Mercury Element

My element is Mercury,the atomic number is 80 and the atomic mass is 200.59.The symbol is Hg.Mercury comes from the greek name hydrargyrum which means liquid silver.The element is also known as quicksilver for its mobility. Named after the fastest-moving planet in the solar system, mercury has been known to humanity for ages.despite its toxic qualities, mercury can still be useful to us. The element conducts electricity and is used in electrical switches of thermostats and certain types of doze alarm-type alarm clocks.It can turn into liquid at room tempurature.It boils at 656.11 F.
Mercury is the only metal that is a liquid at standard temperature and pressure. The only other liquid element under standard conditions is bromine,although the metals rubidium, cesium, and gallium melt just warmer than room temperature. Mercury has a very high surface tension, so it forms rounded beads of liquid.
It accounts for only about only 0.08 parts per million. It is mainly found in the mineral cinnabar, which is mercuric sulfide. Mercuric sulfide is the source the red pigment called vermilion.Mercury generally is not allowed on aircraft because it combines so readily with aluminum, a metal that is common on aircraft. When mercury forms an amalgam with aluminum, the oxide layer that protects aluminum from oxidizing is disrupted. This causes aluminum to corrode, in much the same way as iron
