Pārada (Samskrit: पारद), as mentioned in various Rasashastra texts of ancient India, means Mercury in English. It is a chemical element with atomic number 80 and chemical formula 'Hg (Hydrargyrum)'. Mercury (Hg), a metallic chemical element belonging to the zinc group (Group 12 [IIb] of the periodic table), is the only elemental metal that is liquid at room temperature. Mercury is silvery white, slowly tarnishes in moist air, and freezes into a soft solid like tin or lead at −38.83 °C (−37.89 °F). The chemical symbol Hg derives from the Latin ''hydrargyrum'', “liquid silver.”<ref>Britannica, T. Editors of Encyclopaedia. "mercury." Encyclopedia Britannica, August 20, 2024. <nowiki>https://www.britannica.com/science/mercury-chemical-element</nowiki>.</ref> It is also called Quick Silver, as it appears like silver having the property of flowing.
