Each Oxygen has -2 number.Bromines oxidation number is +5.
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.
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+.
In the compound BrO3-, bromine is more electronegative than oxygen and has an oxidation number of +5 to satisfy the overall charge of the anion which is -1. Each oxygen atom has an oxidation number of -2, so the total oxidation numbers in BrO3- sum up to -1.
BrO3- is an ionic compound. It consists of the bromine ion (Br-) and the polyatomic ion bromate (BrO3-), which is a combination of covalent and ionic bonds.
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.
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 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.
-2 for each O, +5 for Br

Hydrogen's oxidation number is +1.Chlorin's oxidation number is +1.Oxygen's oxidation number is -2.
BrO3
The oxidation number of acetate (CH3COO-) is -1. The carbon atom has an oxidation number of +3, each hydrogen atom has an oxidation number of +1, and the oxygen atoms have an oxidation number of -2.
The oxidation number of each hydrogen in H2CO2 is +1, while the oxidation number of each carbon in CO2 is +4. This is because hydrogen usually has an oxidation number of +1, and oxygen usually has an oxidation number of -2.
