Spencer Kociba CHEM 101 Lecture 10/25/16 ● H, He and B are the only elements that don’t need to fulfill the octet rule (they don’t need to reach 8, but there are elements that can have more than 8 valence electrons because of d orbitals) ● Formal charge ○ Predicts the lewis structure of molecules ○ (valence e)-(all e in lone pairs)-½ (shared e)= Formal charge ○ Ex. vs ○ Valence e 6 4 6 6 4 6 -(e 6 4 6 7 4 5 assigned) Total 0 0 0 -1 0 +1 ○ The more viable option is the first arrangement o
