Step 1I'll solve this problem step by step, focusing on molecular geometry and polarity.
Step 2: Determine the Lewis structure and electron geometry for SiF^4
- Total valence electrons: $$4 + (4 \times 7) = 32$$ electrons
- Silicon (Si) is the central atom - Silicon has 4 valence electrons - Fluorine (F) has 7 valence electrons - Arrangement will be tetrahedral with 4 identical Si-F bonds
Final Answer
- SiF^4: Nonpolar - SF^4: Polar
