Step 1Let's solve this step by step using VSEPR (Valence Shell Electron Pair Repulsion) theory:
Step 2: Determine the number of valence electrons for Xe
- Total valence electrons: $$8 + (2 \times 7) = 22$$ electrons
- Xenon (Xe) is in Group 18 - Xe has 8 valence electrons - Each F contributes 7 valence electrons
Final Answer
Linear, 5 electron groups
