Oxygen group element, any of the six chemical elements making up Group 16 (VIa) of the periodic classification—namely, oxygen (O), sulfur (S), selenium (Se), tellurium (Te), polonium (Po), and livermorium (Lv). The reason is that a majority of metal ores found in the Earth’s crust are sulphides or oxides. A large amount of sulphur is found in underground deposits. The oxygen family, also called the chalcogens, consists of the elements found in Group 16 of the periodic table and is considered among the main group elements. The elements oxygen, sulphur, selenium, tellurium and polonium constitute the 16 th vertical column or VIA group elements in the long form of periodic table. By properties, we mean to say that they exhibit specific characteristics, such as – colourless, odourless, coloured, light, heavy etc. The term chalcogen was first in use by Wilhelm Blitz and Werner Fischer, members of a research group at the University of Hannover in Germany. Tellurium is an element that has properties between metals and non-metals. It is located in compounds with copper, lead, silver, and gold. We inhale oxygen and exhale carbon dioxide. • All noble gases except radon occur in the atmosphere. The elements in this group are also known as the chalcogens or the ore-forming elements because many elements can be extracted from the sulphide or oxide ores. Oxygen, sulphur, and selenium are non-metals. It is the rarest element among the group 16 elements. It has scientific applications for alpha radiations as it is a radioactive element. The group 16 elements react with iodine to form tetra iodides. The chalcogen family is placed under the oxygen classification. Electron density on central atom decreases and consequently its tendency to donate a pair of electron decreases and hence its Acid strength increase. Ionisation enthalpy: Ionisation enthalpy of elements of group 16 is lower than group 15 due to half-filled p-orbitals in group 15 which are more stable. Login. Group-16 Elements.
