More Calculate Oxidation Number SolutionsPost your own question here. Oxidation number (also called oxidation state) is a measure of the degree of oxidation of an atom in a substance (see: Rules for assigning oxidation numbers). We also know here that hydrogen is (+1) and oxygen is (-2). 4 + 4(Br) = 0. a)KBr b)BrF3 c)HBrO3 d)CBr4. Cell atlas. BrF3. a)KBr b)BrF3 c)HBrO3 d)CBr4. Join Yahoo Answers and get 100 points today. Ask Question + 100. Then it is for you to know the possible oxidation state of ‘Br’. The oxidation number of each atom can be calculated by subtracting the sum of lone pairs and electrons it gains from bonds from the number of valence electrons. Br + 3 (-1) = 0. Figure 1.
