Determine bond type and polarity from Pauling electronegativity values
Rule of Thumb: $\Delta\text{EN} < 0.4$ (Nonpolar Covalent), $0.4 \le \Delta\text{EN} \le 1.7$ (Polar Covalent), and $\Delta\text{EN} > 1.7$ (Ionic Bond).

⚠️ Bond classification guidelines $(\Delta\text{EN})$ are general approximations. Actual bond character can also be influenced by molecular geometry, hybridization, resonance, and partial ionic/covalent contributions.
