Rules for Lewis Structures 1. Write the skeletal structure.-Hydrogen cannot be central.-Atoms that occur once are usually central.Example: CBr4 -The least electronegative atom is central.-Use chemical intuition.2. Sum the total number of valence electrons of all atoms.Special - Polyatomic ions...
Yes, there are some exceptions to the octet rule in Lewis structures. Some molecules, such as boron trifluoride (BF3) and sulfur hexafluoride (SF6), have less than 8 valence electrons around the central atom. Other molecules, like phosphorus pentachloride (PCl5) and sulfur hexafluoride (SF6),...
