Match List I with List II:

| List-I (Elements) | List-II (Properties in their groups) |
|---|---|
| A. Cl, S | I. Highest electronegativity |
| B. Ge, As | II. Largest atomic size |
| C. Fr, Ra | III. Properties of both metals and non-metals |
| D. F, O | IV. Highest negative electron gain enthalpy |

Canvas Classes · Accepted Answer

Strategy:
 Match the elements to their unique group properties, focusing on size anomalies, electronegativity peaks, and metalloid characteristics.

Step 1: Match the pairs
- A. Cl, S: These  period non-metals have the highest negative electron gain enthalpy in their respective groups (Anomaly: ). (IV)
- B. Ge, As: Situated along the diagonal in the -block, they are metalloids showing properties of both metals and non-metals. (III)
- C. Fr, Ra: Located at the bottom of Groups 1 and 2, they posse
