-1 in bromide (most common). It can exhibit oxidation numbers from -1 to +7 (in HBrO4)
IF THE FORMULA IS BrO THEN THE OXIDATION NUMBER OF Br SHOULD BE 2, BUT IF IT HAS NET CHARGE OF -1 THEN THE OXIDATION NUMBER OF BROMINE WILL BE +1
If Br had an oxidation number of +7, the net charge on the ion would be +1, and not -1. Thus, the oxidation number for Br in BrO3- should be 5+.
Oxidation number of Br in BrO3 is 6. BrO3 doesn't exist. It should actually be BrO3- ion with +5 oxidation number for Br.
Each Br atom has an oxidation number of zero.
The Potassium (K) has an oxidation number of +1. The Bromine (Br) has an oxidation number of -1.

-2 for each O, +5 for Br
Each Br atom has an oxidation number of zero.
The Potassium (K) has an oxidation number of +1. The Bromine (Br) has an oxidation number of -1.
+1 for Na -1 for Br
Each Br atom has an oxidation number of zero.

The molecular formula should be CBr4. The oxidation numbers are -1 for each Br, +4 for C.
-1 for Cl and +1 for Br
-1 for bromine in bromide
The oxidation number for the molecule Br2 is 0.
