yes it does. It actually has two double bonds.
BrO3
The compound formed with aluminum, bromine, and oxygen is aluminum bromate, which has the chemical formula Al(BrO3)3.
BrO3- is the anion bromate, not a free radical.
The chemical formula for the compound formed between barium and bromine is BaBr2. In this compound, barium forms a +2 cation (Ba^2+) and bromine forms a -1 anion (Br^-), resulting in the formula BaBr2.
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.

Bromate is a polyatomic ion made of Bromine and oxygen: BrO3-
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.
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.
B2O3: Note that the prefix "di-" means two and the prefix "tri-" means three.
There are two resonance structures for bromate - two of the oxygens are double bonded to bromine, and one is single bonded. The double bonded bromines share the electrons between all three, creating two equivalent resonance structures.
The Lewis dot structure for BrO3 -1 consists of Br (Bromine) at the center, with one double bond and two single bonds to O (Oxygen) atoms. One of the oxygen atoms will have a lone pair of electrons. The overall charge of the ion is -1.
No, BrO3 does not have any free radicals. The BrO3 molecule consists of bromine bonded to three oxygen atoms, and there are no unpaired electrons present to form free radicals.
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.
