Mercury has been known since ancient times. Its name derives from the name of the planet Mercury and its symbol drives from the Latin word "hydrargyrum" which means "liquid silver". Mercury’s melting point is at -38.87 °C (234.28 K, -37.966 °F) and its boiling point is at 356.58 °C (629.73 K, 673.844 °F).
