Oxidation state for sodium = 1, So, Two sodium gets (1+1)= 2 . In rare state, oxidation number could be -1. The oxidation number of Cl is -1 in HCl, but the oxidation number of Cl is +1 in HOCl. a.Na = +1, Br = -1, O = 0. b.Na = +1, Br = -1, O = -2. c.Na = -1, Br = -1, O = +2. Fluorine is more electronegative than oxygen. 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. The oxidation number of fluorine is always –1. Group 1 metals in the elemental form, such as hydrogen, lithium and sodium, have an oxidation number of +1; group 2 metals in their elemental form, such as magnesium and calcium, have an oxidation number of +2.
