This element is used to separate the isotopes lithium 6 and lithium 7 in the COLEX process. A compound of this metal, carbon, and hydrogen can lead to neurological damage when ingested in (10[1])Minamata disease. (10[1])Polarography uses a “dropping” electrode of this element, whose chloride, known as calomel, is used (10[1])in many other electrodes. This element’s sulfide forms the mineral cinnabar, which is used in the pigment vermillion. The (10[1])non-metric (10[1])“torr” unit of pressure is approximately (10[2])equal to 1 millimeter of this element. (10[1])For 10 points, amalgams contain what metallic element that is a silvery liquid (10[1])at room temperature? ■END■
