tellurium (Te), semimetallic chemical element in the oxygen group (Group 16 [VIa] of the periodic table), closely allied with the element selenium in chemical and physical properties.

Tellurium is a semiconductor and is frequently doped with copper, tin, gold or silver. Tellurium is also used to color glass and ceramics and is one of the primary ingredients in blasting caps.

Tellurium has eight stable isotopes (Te-120 and Te-123 are usually considered stable because of their long half lives) and many of them have a medical application.

The Chemistry Division's Periodic Table describes the history, properties, resources, uses, isotopes, forms, costs, and other information for each element.

The chemical element tellurium is classed as a chalcogen and a metalloid. It was discovered in 1798 by Martin H. Klaproth.

Tellurium, near the bottom of the family, looks and behaves very much like most metals. The slow change of properties, from less metal-like to more metal-like, occurs in all families in the periodic table.

Tellurium is the 52nd element in the periodic table and has a symbol of Te and atomic number of 52. It has an atomic weight of 127.60 and a mass number of 130. Tellurium has fifty-two protons and …

The primary use of tellurium is in alloys, foremost in steel and copper to improve machinability. Tellurium is used as a basic ingredient in blasting caps, and is added to cast iron for chill control.
