Strategy:
 Identify properties in Group 17 that do not follow a simple monotonic trend. Fluorine often breaks the trend due to its small size and high electron-electron repulsion.

Step 1: Analyze each
- Covalent Radius: F is significantly smaller than expected.
- Electron Affinity: Cl  F is a major irregularity.
- Ionic Radius: Anomalous jumps between periods.
- : F is exceptionally high.

All these properties show characteristic irregularities due to the uniqueness of the Period 2 element (Flu
