BrO3 is an anion of minus one (-1) charge.
BrO3^-1
Using oxygen as the standard at '-2'
Then the oxygen moiety is 3 X -2 = -6
So doing a 'little' sum
-6 + Br = -1
Add '6' to both sides
Br = 5 (The oxidation number of Br).
NB Using '-2' for oxygen is a good standard for most molecules/ions. However, oxygen's oxidation number does vary , but not in very many molecules/ions.

What is the oxidation number of Br in BrO3?
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.
What is the oxidation number for BrO3?
The oxidation number for Br in BrO3 is +5. This is because the overall charge of the BrO3 molecule is -1, and the oxygen atoms have an oxidation number of -2 each. Therefore, the oxidation number of Br must be calculated as +5 to balance the charges.
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 LiBrO3?
LiBrO3 this decomposes to Li^(+) & BrO3^(-) The bromate anion has a charge of '-1' Use the standard for oxygen at '-2' Since there are 3 oxygens then the oxygen moiety is 3 X -2 = -6 Creating a little sum Br + -6( oxygen moiety) = -1( anion charge) Br - 6 = -1 Add '6 'to both sides Br = (+)5 The oxidation state of bromine.
Oxidation number of BR in KBrO3?
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.
What is the oxidation number of Br in BrO3?

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 the BrO3-?
-2 for each O, +5 for Br
What is oxidation number of BrO3?
The oxidation number of Br in BrO3- is +5. This is because oxygen typically has an oxidation number of -2, and since there are three oxygen atoms in the BrO3- ion, the total negative charge is -6. Since the overall charge of the ion is -1, the oxidation number of Br must be +5 to balance the charges.
What is the oxidation number of Br in LiBrO3?
LiBrO3 this decomposes to Li^(+) & BrO3^(-) The bromate anion has a charge of '-1' Use the standard for oxygen at '-2' Since there are 3 oxygens then the oxygen moiety is 3 X -2 = -6 Creating a little sum Br + -6( oxygen moiety) = -1( anion charge) Br - 6 = -1 Add '6 'to both sides Br = (+)5 The oxidation state of bromine.
What is the oxidation number of Br in Br?
-2 for each O, +5 for Br
Oxidation number of BR in KBrO3?
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.
Oxidation number of Br?
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.
What is the oxidation number of PBr5?
The oxidation number of phosphorus in PBr5 is +5. This is because bromine typically has an oxidation number of -1, and there are 5 bromine atoms in PBr5, making the overall charge of the compound neutral.
What is the oxidation numbers of NaBrO2?
In NaBrO2, the oxidation numbers are as follows: Na is +1, Br is +5, O is -2.
What is the oxidation number of bromine in br2?
In the formula NaBrO3, Oxygen will always have a -2 oxidation number. In this case the total number for oxygen in -6 because there are three oxygen atoms. Sodium will always have a +1 oxidation number therefore its total oxidation number is +1. The entire charge has to equal zero so taking what we have now: -6 and +1 we have a -5 left over. Therefore, Bromine must have a +5 oxidation number.
