Best ResponseYou've already chosen the best response.0But my question is that doesn't this structure make the centre atom (S) hypervalent (have an expanded octet)  'S' doesn't obey the octet rule in this structure because if you count the bond pair electrons and lone pairs around S, it sums up to 10 electrons!

Best ResponseYou've already chosen the best response.0I've been told that this dw:1444203681550:dw is not the 'best' Lewis structure because it has a formal charge, but at least it follows the Octet rule.

Best ResponseYou've already chosen the best response.0So, is not having formal charge the most important when it comes to drawing Lewis structures? Or am I missing something?

Best ResponseYou've already chosen the best response.1No, the most important thing is completing the octates (as the name suggests) but in case of sulfur or other 3rd period elements 1st we see if the octate is complete, then we see if the formal charge is least. Since sulfur and other 3rd period elements have a vacant 3d orbital they can expand their octates, so if we can get a structure with less formal charge even if the octate is expanded its ok cz theoretically it will be more stable over all

Best ResponseYou've already chosen the best response.0Ohhh!! Well that makes sense now! So does that only apply to elements in the 3rd period?

Best ResponseYou've already chosen the best response.13rd period and beyond. Not to 1st and 2nd period because they can not expand their octates due to lack of vacant d orbitals.
