The charge of a vanadium ion in the compound V2O5 is:
Oxidation state is the hypothetical charge present on atoms, which can be positive, negative, or zero. If we consider a compound 100% ionic, in that case, all atoms would be ionic and contain some charges on themselves. In the complex, (V,0]; Consider all atoms ionic and contain some charges. The oxidation number of O atom is -2 because it is an anionic ligand. Suppose, the oxidation number of V is “’n”. To calculate the oxidation state of V, add the oxidation numbers of all atoms present in the compound, nx2+(-2)*5=0 nx2=10 n=10 = 5 Hence, in the compound, V,O3, the oxidation state of Vis +5.
