* Boron's Valence Electrons: Boron has 3 valence electrons.
* Bromine's Valence Electrons: Bromine has 7 valence electrons.
* Bonding: Boron forms three single covalent bonds with three bromine atoms.
* Electron Pairs: There are three bonding electron pairs around the boron atom.
* No Lone Pairs: There are no lone pairs on the central boron atom.
According to VSEPR theory (Valence Shell Electron Pair Repulsion), the electron pairs around the boron atom will arrange themselves as far apart as possible to minimize repulsion. This results in a trigonal planar shape with bond angles of 120 degrees.
