Word Origin for tellurium
metallic element, named by German chemist and mineralogist Martin Heinrich Klaproth (1743-1817) from Latin tellus (genitive telluris) "earth" (see tellurian).
- A brittle metallic element usually found in combination with gold and other metals, used to alloy stainless steel and lead, and in thermoelectric devices. Atomic number 52.
