Obviously sulfur has 6 electrons in its outer shell but how many can it accept? Ive seen sources online say 6 more electrons to form 6 covalent bonds but what about dative bonds? Would 6 still be the maximum then? My initial thought was that it might be able to take 18 since the 3rd shell is 3s2 3p6 3d10 but then 4s fills up before 3d so that probably isn't right? Thank you!!
