Step 1I'll solve this step by step, focusing on drawing the correct Lewis structure for sulfur dioxide (\mathrm{SO}_{2}).
Step 2: Determine the total number of valence electrons
- Total valence electrons: $$6 + (6 \times 2) = 18$$ electrons
- Sulfur (S): 6 valence electrons - Oxygen (O): 6 valence electrons × 2 atoms
Final Answer
C (\mathrm{O}=\mathrm{S}=\mathrm{O}) is the correct Lewis structure for sulfur dioxide.
