The difference between electron gain enthalpies will be maximum between:
- a
Ne and F
- b
Ar and F
- c✓
Ne and Cl
- d
Ar and Cl
Ne and Cl
Electron gain enthalpies (approximate values):
| Element | EGE (kJ/mol) | |---|---| | F | −328 | | Cl | −349 | | Ne | +116 | | Ar | +96 |
Differences:
- Ne and F: kJ/mol
- Ar and F: kJ/mol
- Ne and Cl: kJ/mol ← maximum
- Ar and Cl: kJ/mol
The maximum difference is between Ne (+116) and Cl (−349).
Answer: Option (3) — Ne and Cl
