The chalcogens (ore forming) ( / ˈkælkədʒənz / KAL-kə-jənz) are the chemical elements in group 16 of the periodic table. [1] This group is also known as the oxygen family. Group 16 consists of the elements oxygen (O), sulfur (S), selenium (Se), tellurium (Te), and the radioactive elements polonium (Po) and livermorium (Lv). [2]

17 de sept. de 2018 · This Minireview provides an overview on the origin and features of chalcogen bonding as well as its applications in the solid state and in solution. A certain focus will be on the latter and particularly on the recent introduction of chalcogen bonding in noncovalent organocatalysis.
Catenation is the bonding between the same chalcogen atoms, and both simple substances and ions of chalcogens take a variety of structures. The major isotopes of sulfur are 32 S (95.02% abundance), 33 S (0.75%), 34 S (4.21%), and 36 S (0.02%), and there are also six radioactive isotopes.
