* Br3 (Tribromide) is a polyatomic ion, not a molecule. It has a linear structure with one bromine atom in the center and two bromine atoms bonded to it.
* Polar bonds occur when two atoms with different electronegativity values share electrons. The more electronegative atom attracts the shared electrons more strongly, creating a partial negative charge (δ-) on that atom and a partial positive charge (δ+) on the less electronegative atom.
* Bromine has an electronegativity value of 2.96. Since all the atoms in the Br3 ion are bromine, they have the same electronegativity.
Therefore, there are no polar bonds present in Br3. The bonds between the bromine atoms are nonpolar covalent bonds.
