Mercury vapor is odorless, colorless and very toxic. Even though liquid mercury evaporates slowly, a significant amount of mercury vapor can build up indoors after mercury is spilled, and it can be dangerous to breathe these mercury vapors.
Because of its toxicity, the clinical use of mercury and mercurials is diminishing. Mercury is an element with atomic symbol Hg, atomic number 80, and atomic weight 200.59; a heavy, silvery-white metal, liquid at room temperature, a rather poor conductor of heat and a fair conductor of electricity.
