Oxidation number of element in a compound can be positive or negative or may be zero. ∴ x+3−2+1 = 0. To determine the oxidation state of simple inorganic compounds, you assume that the oxidation state of all but one of the elements in the compound is known and determine the remaining element by difference, since the sum of all oxidation number must be zero. The oxidation number is negative in sign if its electronegativity is high in case of a more electronegative atom. However, in the air, oxidation does generally involve the reaction of a chemical species with an oxygen containing compound. Copyright © 2020 Multiply Media, LLC.
