Tellurium is a chemical element; it has symbol Te and atomic number 52. It is a brittle, mildly toxic, rare, silver-white metalloid. Tellurium is chemically related to selenium and sulfur, all three of which are chalcogens. It is occasionally found in its native form as elemental crystals.
The main source of tellurium is from copper anode slimes, which contain precious metals as well as various tellurides. These slimes are roasted with sodium carbonate and oxygen to produce sodium tellurite. [1] Ag 2 Te + Na 2 CO 3 + O 2 → 2Ag + Na 2 TeO 3 + CO 2 (400–500 °C) This is a reaction with silver telluride.

Historically the name tellurate was only applied to oxyanions of tellurium with oxidation number +6, formally derived from telluric acid Te(OH) 6, and the name tellurite referred to oxyanions of tellurium with oxidation number +4, formally derived from tellurous acid (HO) 2 TeO and these names are in common use.
tellurium-128: 2.2 69 The half-life of tellurium-128 is over 160 trillion times greater than the age of the universe, which is 4.35 ...
Tellurite is a rare oxide mineral composed of tellurium dioxide (Te O 2).. It occurs as prismatic to acicular transparent yellow to white orthorhombic crystals. It occurs in the oxidation zone of mineral deposits in association with native tellurium, emmonsite and other tellurium minerals.
Gold chalcogenides are compounds formed between gold and one of the chalcogens, elements from group 16 of the periodic table: oxygen, sulfur, selenium, or tellurium. Gold(III) oxide, Au 2 O 3. Decomposes into gold and oxygen above 160 °C, and dissolves in concentrated alkalis to form solutions which probably contain the [Au(OH) 4] − ion
