* Central Atom: Bromine (Br) is the central atom.

* Valence Electrons: Bromine has 7 valence electrons, and each chlorine (Cl) atom has 7.

* Bonding: Bromine forms three single bonds with three chlorine atoms.

* Lone Pairs: Bromine has two lone pairs of electrons.

The two lone pairs on the central atom repel the bonding pairs, pushing the three chlorine atoms into a T-shape.

Let me know if you'd like a diagram of the molecular shape!
