![]() ![]() ![]() Its molecular geometry, polarity, and reactivity can be determined by observing the corresponding Lewis structure. The Lewis structure of a compound helps predict many of its properties. Thus, the total number of valence electrons in Cobalt Dichloride is given by:Ģ + 14 = 16 valence electrons. Therefore, the two Chlorine atoms present in CoCl 2 contribute 7 x 2 = 14 valence electrons. The possibility of electrons in its d shell makes it hypervalent. Chlorine’s electronic configuration is given by 3s 2 3p 5. Therefore, a single Cobalt atom contributes 2 x 1 = 2 Valence electrons.īeing in group 7 of the periodic table, Chlorine has seven valence electrons with a valency of -1. This allows the electrons to break free of the atom during exchanges.ĬoCl 2 comprises a Cobalt atom flanked by two Chlorine atoms on either side.īeing in group 9 (transition metals) of the periodic table, Cobalt has an electronic configuration of 3d 7 4s 2. These electrons are present in the outermost shell, where the force of attraction from the nucleus is the weakest. Valence electrons are those electrons that are available to be used during bond formation. These building blocks are the valence electrons contributed by the constituent atoms. To form Lewis structures, we need to know more about the building blocks that help make them. CoCl2 Molecular Geometry and Bond Angles.It has the following properties: Name of the molecule It has a history of being used to induce hypoxia-like responses such as erythropoiesis. Cobalt Dichloride has been marked as a ‘substance of concern’ and a potential carcinogen by the European Chemical Agency. Cobalt is essential to most large-bodied organisms, but an excess of the element can cause adverse effects. This ease of hydration and dehydration makes Cobalt Dichloride a good indicator of hydration in desiccants and humidity.ĬoCl 2 occurs freely in nature and can be found in rocks and minerals. These versions of the salt are purple and pink, respectively. It occurs at different levels of hydration as dehydrates and hexahydrates. It is readily soluble in water, alcohol, and acetone. CoCl 2 is a crystalline solid that is sky-blue in color. It is an inorganic compound that comprises Cobalt and Chlorine atoms. The chemical formula CoCl 2 represents Cobalt (II) Chloride. ![]()
