WebMay 19, 2012 · In fact, there is a duet rule to be considered for hydrogen, helium (and lithium which dimerizes in the gas phase), and the 'rule of 18' for transition metals. Where things get 'wonky' are silicon through chlorine. These atoms can form a complete quantum shell via the octet rule, or 'expand' their octets and be governed by the rule of 18. Web2 days ago · Sulfur can expand its octet and can accommodate up to 12 electrons because of which, it does not follow the octet rule. Sulfur can do so as it has access to energetic 3d-subshell for bonding. As there is a small energy difference between 3p and 3d shells, with the help of a little excitation, an unpaired electron can move from the 3p shell … sharepoint online email scam
