WebSulfur, phosphorus, silicon, and chlorine are common examples of elements that form an expanded octet. Phosphorus pentachloride (PCl 5) and sulfur hexafluoride (SF 6) are examples of molecules that deviate from the octet rule by having more than 8 electrons around the central atom. Key Terms The octet rule is a chemical rule of thumb that reflects the theory that main-group elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas. The rule is especially applicable to carbon, nitrogen, oxygen, and the halogens; although more generally the rule is applicable for the s-block and p-block of the periodic ta…

The Octet Rule: Definition & Examples StudySmarter
WebJan 30, 2024 · The octet rule should be applied to HNO 3, NO − 3, H 2CO 3, CO2 − 3, C 5H 5N, C 6H 6, and Cl 2CO. Exceptions to the octet rule We can write Lewis dot structures that satisfy the octet rule for many molecules consisting of main-group elements, but the octet rule may not be satisfied for a number of compounds.
