Step 1I'll solve this step by step, focusing on drawing the correct Lewis structure for ammonia (NH3).
Step 2: Determine the total number of valence electrons
- Total valence electrons: $$5 + (3 \times 1) = 8$$ valence electrons
- Nitrogen (N) has 5 valence electrons - Hydrogen (H) has 1 valence electron
Final Answer
The correct Lewis structure for ammonia (NH3) has: - Nitrogen at the center - Three single bonds to hydrogen atoms - One lone pair of electrons on the nitrogen atom The structure looks like a trigonal pyramidal arrangement with the lone pair at the top of the pyramid.
