Tellurium dioxide is formed by heating tellurium in air, where it burns with a blue flame. [43] Tellurium trioxide, β-TeO 3, is obtained by thermal decomposition of Te(OH) 6. The other two forms of trioxide reported in the literature, the α- and γ- forms, were found not to be true oxides of tellurium in the +6 oxidation state, but a mixture ...
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.
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]
The earliest phase of the seaway began in the mid-Cretaceous when an arm of the Arctic Ocean transgressed south over western North America; this formed the Mowry Sea, so named for the Mowry Shale, an organic-rich rock formation. [1] In the south, the Gulf of Mexico was originally an extension of the Tethys Ocean. In time, the southern embayment ...
Polymetallic nodules are found within the Mid-Atlantic Ridge system, around Papua New Guinea, Solomon Islands, Vanuatu, and Tonga, [22]: 356 and the Peru Basin. [38] Cobalt-rich crusts are found on seamounts in the Atlantic and Indian Ocean, as well as countries such as the Pacific Federated States of Micronesia, Marshall Islands, and Kiribati.
The Altamaha River / ˈ ɑː l t ə m ə h ɑː / is a major river in the U.S. state of Georgia.It flows generally eastward for 137 miles (220 km) from its origin at the confluence of the Oconee River and Ocmulgee River towards the Atlantic Ocean, where it empties into the ocean near Brunswick, Georgia.

Selenium is named after the Greek goddess of the moon, Selene, to match the previously discovered element tellurium, whose name comes from the Latin word telus, meaning earth. Polonium is named after Marie Curie's country of birth, Poland. [7] Livermorium is named for the Lawrence Livermore National Laboratory. [53]
