Whether sulfur or phosphorous actually expand their octet is contested within the chemistry community. Another term for this octet expansion is "hypervalency." You can find many works of research regarding hypervalency. The consensus, according to Wikipedia, is that both can expand their octets, but not to a significant extent.

WebThese molecules feature 3c-2e bonds (three centred bonds) in which two electrons are shared by three atoms. The Expanded Octet – Hypervalency. Some main group elements have the ability to form hypervalent compounds. Examples include sulfur hexafluoride (SF 6) and phosphorus pentachloride (PCl 5). WebOct 5, 2024 · Answer: see below Explanation: Sulfur and phosphorous can violate the octet rule and have an expanded octet, so molecules of these elements can contain more than eight valence electrons. In contrast, nonmetal elements in period 2 can't have an expanded octet because they don't have d orbitals.
