Answer
Answer:
B. PCl5 because a subscript of 5 indicates five Cl atoms
Explanation:
Step1: Understand compound naming
In phosphorus pentachloride, "penta -" means five and it refers to the number of chlorine atoms.
Step2: Analyze chemical formula
The symbol for phosphorus is P and for chlorine is Cl. Since there are five chlorine atoms bonded to one phosphorus atom, the formula is PCl5.
