The oxidation level of Br can vary depending on the compound it is in. In the compound HBr, the oxidation level of Br is -1. In Br2, the oxidation level of Br is 0.
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+.
The oxidation number of Li in LiBr is +1, and the oxidation number of Br is -1.
The oxidation number of Br in KBrO3 is +5. This is because oxygen typically has an oxidation number of -2 and the overall compound has a neutral charge. Since there is only one Br atom in KBrO3 and the oxidation numbers of K and O are known, the oxidation number of Br can be calculated as +5 to balance the overall charge.
The oxidation number of Br in BrO3 is +5. This is because the oxidation number of oxygen is usually -2, and since there are three oxygen atoms in BrO3, the total negative charge from oxygen is -6. To balance the charge of the compound which is neutral, the oxidation number of Br is therefore +5.
The oxidation number of Br in ZnBr2 is -1. In ZnBr2, zinc (Zn) has an oxidation number of +2, so the two bromine (Br) atoms each have an oxidation number of -1 to balance the charge of the compound.
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+.
-2 for each O, +5 for Br
The oxidation number of Li in LiBr is +1, and the oxidation number of Br is -1.
The oxidation number of Br in KBrO3 is +5. This is because oxygen typically has an oxidation number of -2 and the overall compound has a neutral charge. Since there is only one Br atom in KBrO3 and the oxidation numbers of K and O are known, the oxidation number of Br can be calculated as +5 to balance the overall charge.

The oxidation number of Br in ZnBr2 is -1. In ZnBr2, zinc (Zn) has an oxidation number of +2, so the two bromine (Br) atoms each have an oxidation number of -1 to balance the charge of the compound.
+1 for Na -1 for Br
To balance the equation Br₂ + Br⁻ + BrO₃⁻, you can follow these steps: Start by identifying the oxidation states of bromine in each species. Br₂ is in the 0 oxidation state, Br⁻ is -1, and BrO₃⁻ has bromine in the +5 oxidation state. Balancing the half-reactions for reduction and oxidation, you find that the balanced equation is: 3 Br₂ + 6 Br⁻ + 6 H₂O → 6 BrO₃⁻ + 12 H⁺.
The oxidation number of Br- is -1. Bromine typically has an oxidation state of -1 when it forms an ion by gaining one electron.
The oxidation number of Br in Al2Br6 is -1. This is because the overall charge of the compound must be zero, and since we have two Br atoms each at -1 oxidation state, it balances out with the +3 oxidation state of Al.
In Br₂O₃ (dibromine trioxide), bromine (Br) typically has an oxidation number of +3 because oxygen (O) usually has an oxidation number of -2. Br₂O₃ is a neutral compound, so the sum of the oxidation numbers of each element must add up to zero.
The Potassium (K) has an oxidation number of +1. The Bromine (Br) has an oxidation number of -1.
