Bromine is in the seventh family on the Periodic Table. That means that it has seven valence electrons. It wants to have eight valence electrons to be stable, so it will gain an electron, making it negative. The oxidation number of Br is Br-1.

∙ 8y agoThat depends on the substance it is part of.
In the element, the OS is zero.
In many compounds, such as metal bromides, it is -1.
It also forms compounds where its OS is +7, +5, +3 and +1.

What is the oxidation number for Br in BrO3-?
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+.
What is the oxidation number of Br in BrO3?
Oxidation number of Br in BrO3 is 6. BrO3 doesn't exist. It should actually be BrO3- ion with +5 oxidation number for Br.
What is the oxidation number of Br2?
Each Br atom has an oxidation number of zero.
What is the oxidation number of KBr?
The Potassium (K) has an oxidation number of +1. The Bromine (Br) has an oxidation number of -1.
