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.
Minerals containing the chemical element tellurium Note (New Dana Classification): Telluride minerals are in the category: Sulfides and Sulfosalts (sulfides, selenides, tellurides; arsenides, antimonides, bismuthides; sulfarsenites, sulfantimonites, sulfbismuthites, etc.) too
There are 39 known isotopes and 17 nuclear isomers of tellurium (52 Te), with atomic masses that range from 104 to 142. These are listed in the table below. Naturally-occurring tellurium on Earth consists of eight isotopes. Two of these have been found to be radioactive: 128 Te and 130 Te undergo double beta decay with half-lives of, respectively, 2.2×10 24 (2.2 septillion) years (the longest ...

Tellurite is a oxyanion of tellurium with the formula TeO 2− 3. It is the ion of tellurous acid, and is chemically related to tellurium dioxide (TeO 2), whose mineral appearance also bears the name tellurite. Tellurites are typically colorless or white salts, which in some ways are comparable to sulfite. [3]

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.
When the South Vietnamese regime threatened to block Nhất Hạnh's reentry to the country, Merton wrote an essay of solidarity, "Nhat Hanh is my Brother". [40] Between June and October 1963, Nhất Hạnh conducted numerous interviews with newspapers and television networks to rally support for the peace movement. [ 41 ]
