Yahoo fait partie de Verizon Media. If we take Cao then we will get the oxidation state of calcium Let oxidation state of calcium be x. X+1(-2)=0X-2=0 so X=2.Now we take Caocl2.So, 2+1(-2)+2=0. It can react with chlorides, however, to make the very reactive chlorochromate ion CrO3Cl(-) and it can also be used to make the even more reactive CrO2Cl2. = +1) 2 chlorines (oxidation no. = 0) 1 carbon (oxidation no. iv. The elements in which the last electron enters the f-orbital of the antepenultimate (third to the outermost) shell i.e (n 2) f-orbital are called f-block elements. Generally the oxidation state of oxygen and chloride is -2 & -1 as they belongs to the VIA and VIIA group respectively. You may need to download version 2.0 now from the Chrome Web Store.
