Beschrijving

Bol Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online.The chalcogens are the chemical elements in group 16 (old- style: VIB or VIA) of the periodic table. This group is also known as the oxygen family. It consists of the elements oxygen (O), sulfur (S), selenium (Se), tellurium (Te), the radioactive element polonium (Po), and the synthetic element ununhexium (Uuh). The name means "ore former" from the Greek chalcos = ore and -gen = formation. Although all group 16 elements of the periodic table, including oxygen are defined as chalcogens, oxygen and oxides are usually distinguised from chalcogens and chalcogenides. The term chalcogenide is more commonly reserved for sulfides, selenides, and tellurides, rather than for oxides. Oxides are usually not indicated as chalcogenides.
