Tellurium Te - PubChem

Tellurium is a relatively rare element, in the same chemical family as oxygen, sulfur, selenium, and polonium: oxygen and sulfur are nonmetals, polonium is a metal, and selenium and tellurium are semiconductors (i.e., their electrical properties are between those of a metal and an insulator). Nevertheless, tellurium, as well as selenium, is often referred to as a metal when in elemental form.
