noun, Chemistry.
a rare, lustrous, brittle, crystalline, silver-white element resembling sulfur in its properties, and usually occurring in nature combined with gold, silver, or other metals of high atomic weight: used in the manufacture of alloys and as a coloring agent in glass and ceramics. Symbol: Te; atomic weight: 127.60; atomic number: 52; specific gravity: 6.24.
a brittle silvery-white nonmetallic element occurring both uncombined and in combination with metals: used in alloys of lead and copper and as a semiconductor. Symbol: Te; atomic no: 52; atomic wt: 127.60; valency: 2, 4, or 6; relative density: 6.24; melting pt: 449.57±0.3°C; boiling pt: 988°C

tellurium tel·lu·ri·um (tě-lur’ē-əm)
Symbol Te
A brittle metallic element usually found in combination with gold and other metals, used to alloy stainless steel and lead, and, as bismuth telluride, in thermoelectric devices.
