Phosphorus pentachloride (pcl 5) and sulfur hexafluoride (sf 6) are examples of molecules that deviate from the octet rule by having more. Recall that the octet rule states that an element is surrounded by eight electrons in the lewis structure. You’ll know to draw an expanded octet when the central atom is bonded to more than 4 elements.

Elements in the third row of the periodic table never have expanded octets. Some main group elements have the ability to form hypervalent compounds. Which of the following elements cannot form an expanded octet as the central atom? N=3 or higher) can form compounds with an expanded octet.
