Mega Review2Lewis Structure1. Count the total number of valence electrons2. Draw the structure of the molecule and count the number of electrons in the form of bonds1 bond = 2 electrons3. Draw lone pairs to fulfill the Octet Rule4. Calculate the Formal Charge and put appropriate charges on the atoms5. Check if there is a more stable resonance form

Mega Review5Formal ChargeFormal Charge= [number of valence electrons on atom] – [non-bonded electrons + number of bonds]Non-bonded electrons: 1 for each electronNumber of bonds: 1 for each bond
