Step 1I'll solve this problem step by step, following the LaTeX formatting guidelines precisely:
Step 2: Understand the Octet Rule
The octet rule states that atoms tend to combine in such a way that they each have eight electrons in their valence shell. Molecules that have more or fewer than eight electrons in their valence shell may violate this rule.
Final Answer
Yes, PF^5 violates the octet rule with an expanded octet. The central phosphorus atom has 10 electrons in its valence shell, which is two more than the standard octet of 8 electrons.
