Step 1Let's solve this step by step using VSEPR (Valence Shell Electron Pair Repulsion) theory:
Step 2: Determine the number of valence electrons
- Nitrogen (N): 5 valence electrons - Oxygen (O): 6 valence electrons × 3 oxygen atoms = 18 electrons - Negative charge adds 1 electron - Total valence electrons: 5 + 18 + 1 = 24 electrons
Final Answer
Trigonal planar
