The correct Answer is:
To solve the question, "F₂ combines with all non-metals directly except," we need to analyze the reactivity of fluorine (F₂) with various non-metals. ### Step-by-Step Solution: 1. **Understanding Fluorine's Reactivity**: Fluorine is the most electronegative element and is highly reactive. It tends to react with most non-metals to form fluorides. 2. **Identifying Non-Metals**: Common non-metals include hydrogen (H), oxygen (O), nitrogen (N), phosphorus (P), sulfur (S), and the noble gases like xenon (Xe) and krypton (Kr). 3. **Analyzing Reactions with Non-Metals**: - **Hydrogen (H)**: F₂ reacts with H to form HF (hydrofluoric acid). - **Oxygen (O)**: F₂ reacts with O to form OF₂ (oxygen difluoride). - **Phosphorus (P)**: F₂ reacts with P to form PF₅ (phosphorus pentafluoride). - **Sulfur (S)**: F₂ reacts with S to form SF₆ (sulfur hexafluoride). - **Xenon (Xe)**: F₂ can react with Xe to form compounds like XeF₂, XeF₄, and XeF₆. - **Krypton (Kr)**: F₂ reacts with Kr to form KrF₂. 4. **Examining Nitrogen (N)**: When considering nitrogen (N₂), it has a very strong triple bond (N≡N) with a high bond dissociation energy. This makes it less reactive towards fluorine. Therefore, F₂ does not react directly with N₂. 5. **Conclusion**: The only non-metal that F₂ does not combine with directly is nitrogen (N₂). ### Final Answer: F₂ combines with all non-metals directly except nitrogen (N₂). ---
