🧠 The VSEPR Blueprint
Determining lone pairs is a simple accounting job. We need to look at Chlorine's valence electrons and see how many are "working" (bonded) and how many are "idle" (lone pairs).

🗺️ The Electron Audit
1. Central Atom: Chlorine () has 7 valence electrons.
2. Bonding: It forms  single bonds with three Fluorine atoms. This uses  electrons.
3. Remaining:  electrons stay as non-bonding electrons.
4. Pairs:  electrons  lone pairs.
5. Geometry: With  bond pairs and  lone pairs (
