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 Minamata disease. (10[1])Polarography (10[1])uses a “dropping” electrode of this element, whose chloride, known as calomel, is used in many other electrodes. (-5[1])This element’s sulfide forms the mineral cinnabar, (10[2])which (10[1])is used in the (10[1])pigment (10[1])vermillion. The non-metric (10[1])“torr” unit of pressure is approximately equal to 1 millimeter of this element. For 10 points, amalgams contain what metallic element that is a silvery liquid at room temperature? ■END■
