Step 1I'll solve this problem step by step, following the specified LaTeX formatting guidelines:
Step 2: Determine the total number of valence electrons
Total valence electrons: $$7 + 18 + 1 = 26$$ electrons
- Bromine (Br): 7 valence electrons - Oxygen (O): 6 valence electrons × 3 = 18 valence electrons - Negative charge: + 1 electron
Final Answer
The Lewis structure of BrO_{3}^{-} follows the octet rule with: - 26 total valence electrons - Tetrahedral electron geometry - Trigonal pyramidal molecular geometry - Ideal bond angle of 109.5°
