This element is used to separate the isotopes lithium 6 and lithium 7 in the COLEX process. A compound of this metal, carbon, (10[2])and hydrogen can lead to neurological damage when ingested in Minamata disease. (10[1])Polarography uses a “dropping” electrode of this element, (10[1])whose chloride, known as calomel, (10[1])is used in (10[2])many (10[1])other electrodes. (10[1])This element’s sulfide forms the mineral cinnabar, (10[1])which is used in the (-5[1])pigment vermillion. The (-5[1])non-metric “torr” unit of pressure is approximately (10[1])equal to 1 millimeter of this element. (10[1])For 10 points, amalgams contain what metallic element that is a silvery liquid at room (10[1])temperature? (10[1])■END■ (10[1])
