Step 1Before diving into the solution, let's recall the relevant concept and formula:
- VSEPR Theory (Valence Shell Electron Pair Repulsion): This theory helps us predict molecular geometry based on the repulsion of electron pairs in the valence shell of the central atom. Now, let's solve the problem step-by-step:
Step 2
Identify the central atom and the number of electron pairs around it. - The central atom in PF^3 is Phosphorus (P). - Phosphorus has 5 electrons in its outer shell, and each Fluorine atom contributes 1 electron, resulting in a total of 6 electron pairs. \text{Central atom: } \mathrm{P}, \text{ Total electron pairs: } 6
Final Answer
The molecular geometry of the PF^3 molecule is T-shaped, and this molecule is nonpolar.
