This element is bonded to four iodine atoms in Nessler's reagent, which it can precipitate out of when reacted with ammonia. This metal is found in the red pigment vermilion, since it is bonded to sulfur in cinnabar. Alloys of this metal used for dental fillings are called (*) amalgams. Measuring the height of this element in a column can determine pressure, with 760 millimeters corresponding to 1 atmosphere, and this element is also present in some thermometers. For ten points, identify this toxic metal that is liquid at room temperature with
