A group (or family) of elements is a column on the Periodic Table. All elements in a group share the same sorts of characteristics. All elements in the same group have the same amount of electrons ...
Properties and Periodic Trends. Properties of oxygen are very different from other elements of the group, but they all have 2 elections in the outer s orbital, and 4 electrons in the p orbitals, usually written as s 2 p 4. The electron configurations for each element are given below:
22.4 The Elements of Group 16 (The Chalcogens) Learning Objective. To understand the trends in properties and reactivity of the group 16 elements: the chalcogens. The chalcogens are the first group in the p block to have no stable metallic elements. All isotopes of polonium (Po), the only metal in group 16, are radioactive, and only one element ...
All the elements of group 16 form hydrides of the type H 2 M (where M=O,S,Se,Te or Po). The stability of hydrides decreases as we go down the group. Except H 2 O, all other hydrides are poisonous foul smelling gases. Their acidic character and reducing nature increases down the group.
The group 16 elements of modern periodic table consist of 5 elements oxygen, sulphur, selenium, tellurium and polonium. The elements in this group are also known as the chalcogens or the ore-forming elements because a large number of elements can be extracted from the sulphide or oxide ores.
The Oxygen Family . Group 16 (VIA) consist of oxygen, sulphur, selenium, tellurium, and polonium.They are often referred to as the chalcogens and their compounds as the chalcogenides, although these names are seldom applied to oxygen and its many compounds.Oxygen, sulphur, and selenium are non-metals. Tellurium is a metalloid and polonium is a metal.
The chalcogens are the name for the periodic table group 16 (old-style: VIB or VIA) in the periodic table. It is sometimes 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 regular oxidation states showed by the elements of group 16 incorporate -2, +2, +4, and + 6. Chemical Properties. The group sixteen elements react with hydrogen to form hydrides of the sort H 2 E, where E could be any element- oxygen, sulfur, selenium, tellurium or polonium. The Physical States of Hydrides of Group 16 Elements
Chapter 16 Group 16 Elements Physical Properties The elements Halides, oxohalides, oxides, salts of oxoacids Metal sulfides, polysulfides, polyselenides, polytellurides Compounds of sulfur and selenium with nitrogen. 2 Relative abundances of the group 16 elements in the Earth’s crust
The chalcogens (/ ˈ k æ l k ə dʒ ɪ n z /) are the chemical elements in group 16 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), and the radioactive element polonium (Po). The chemically uncharacterized synthetic element livermorium (Lv) is predicted to be a chalcogen as well.
