A brittle, silvery-white metallic element that is used in alloys, ceramics, and thermoelectric devices, often found with other metals.
Tellurium is used in the production of thermoelectric materials.
Tellurium is derived from the Latin word "tellus" (meaning earth). The suffix "-ium" is commonly used in chemistry to denote metallic elements. Thus, tellurium refers to an element associated with the earth.
Think of 'tellus' meaning earth, and remember that tellurium is an element related to the earth.
