The Lewis structure for PCl3 (phosphorus trichloride) can be described as follows:
- Phosphorus (P) is the central atom.
- Phosphorus forms three single bonds with three chlorine (Cl) atoms.
- Phosphorus has one lone pair of electrons.
- Each chlorine atom has three lone pairs of electrons.
Therefore, the correct statement is: Phosphorus has three single bonds and one lone pair of electrons. Each chlorine has one single bond and three lone pairs of electrons.
