WebChromate is an ion that contains one chromium atom (in its +6 oxidation state) and four oxide atoms. Its formula is CrO 4. Its overall charge is -2. Dichromate is similar, but it contains two chromium atoms and seven oxide atoms (therefore, Cr 2 O 7 ). WebChromium (II) hydroxide has the formula Cr (OH)2. Chromium has a 2+ charge and the hydroxide ion has a 1- charge, so two anions are needed to balance the charge of the cation. How many chloride ions will be found in the formula for cobalt (II) chloride? The formula for cobalt (II) chloride is CoCl2 so there are 2 chloride ions in the compound.
