[te-loo r-ee-uh m]
- 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.
