132/-! ## Falsification Criteria
133
134The electron affinity derivation is falsifiable:
135
1361. **Sign violation**: If noble gases have positive EA (they should be ≤ 0).
137
1382. **Halogen not maximum**: If any halogen does NOT have maximum EA in its period.
139
1403. **Ordering violation**: If EA ordering doesn't follow "closer to closure = higher EA"
141 for main group elements (allowing d/f-block anomalies).
142
143Note: Actual EA values in eV are NOT predicted without a scale anchor.
144Only the ORDERING and SIGNS are fit-free predictions.
