A solution of Te 2+ 4. When tellurium is treated with concentrated sulfuric acid, the result is a red solution of the Zintl ion, Te 2+ 4. [53] The oxidation of tellurium by AsF 5 in liquid SO 2 produces the same square planar cation, in addition to the trigonal prismatic, yellow-orange Te 4+ 6: [38]
Tellurium compounds are compounds containing the element tellurium (Te). Tellurium belongs to the chalcogen (group 16) family of elements on the periodic table, which also includes oxygen, sulfur, selenium and polonium: Tellurium and selenium compounds are similar.

Sylvanite crystallizes in the monoclinic 2/m system. Crystals are rare and it is usually bladed or granular. It is very soft with a hardness of 1.5–2. It has a high relative density of 8–8.2. Sylvanite is photosensitive and can accumulate a dark tarnish if it is exposed to bright light for too long.
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 ...
Doraemon tries to help Noby with his exams by giving him some Memory Bread that allows him to retain whatever information is imprinted on it. However, while getting some extra notes from Sue after failed attempts from Ace Goody (who never uses notes due to his photographic memory), Sneech (whose notes were digital), and Big G (whose notes are covered in a gross substance), Noby ends overeating ...
