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[7])Polarography (10[4])uses (10[1])a “dropping” (10[3]-5[1])electrode (10[2]-5[1])of this element, (10[1])whose chloride, known as calomel, (10[3])is used (10[1]-5[1])in many (10[3])other electrodes. (10[1]-5[2])This element’s sulfide forms the mineral (10[1])cinnabar, (10[6]-5[1])which (10[2])is (10[1])used (10[1])in the (10[1])pigment (10[1])vermillion. (10[2])The (10[1]-5[1])non-metric (10[2]-5[1])“torr” unit of pressure (10[2]-5[1])is approximately (10[3])equal to 1 (10[1])millimeter (10[2])of this (10[1])element. (10[4])For 10 points, amalgams contain what metallic element that is a silvery liquid (10[1])at room (10[1])temperature? (10[1])■END■ (10[5])
