Calculate the Oxidation number of Sulphur in S 2 O 8 2-ion. Our strategy, which could be applied to other classes of 2D materials upon proper choice of the oxidation/etching reagent, supports 2D material-based device applications, e.g., in electronics or optoelectronics, where a precise control over the number of layers (hence over the material's physical properties) is needed. Oxidation number in simple terms can be described as the number that is allocated to elements in a chemical combination.
