Sulfur, phosphorus, silicon, and chlorine are … WebNov 2, 2024 · Re: Extended Octet for Sulfur. Sulfur can have an expanded octet because it is in Row 3 of the periodic table, meaning that the quantum number n is equal to 3. When n=3, l can be 0, 1, or 2 according to the rules for quantum numbers. This means that elements in Row 3 have the S, P, and D subshells available to them to hold electrons.

WebJun 27, 2014 · The consensus, according to Wikipedia, is that both can expand their octets, but not to a significant extent. In other words, d-orbital utilization is low at best. Regarding sulfur trioxide, this article may be of interest. We find no evidence to support notions of p π –d π back-donation from oxygen to sulfur. WebCHEM-111G-GENERAL CHEMISTRY I The octet rule indicates that: 1. the noble gases react with other compounds to get 8 valence electrons. 2. all of the noble gases have eight total electrons. 3. all of the shells in an atom hold a maximum of 8 electrons. 4. all of the Group A elements have 8 valence electrons.

WebNov 15, 2024 · Any element in period 3 or below (4, 5, etc.) can have an expanded octet because there are d-orbitals starting with period n = 3. Hi, to add on, Be, Li, H, He, and radicals are also exceptions to the octet rule. Radicals are compounds with unpaired electrons. Hope this helps!
