Give me answer
The oxidation number of Li in LiBr is +1, and the oxidation number of Br is -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.
The oxidation number of Br in BrO is +1. This is because oxygen is typically assigned an oxidation number of -2, and the overall charge of the compound is 0 since there are no additional elements present. Therefore, the oxidation number of Br must be +1 in order to balance the charges.
-1 for bromine in bromide
The oxidation number for the molecule Br2 is 0.
