Shorthand method

Drawing Lewis Structures:

1. Total valance e-

2. Central atom (CA)

3. Single bonds

4. Add non-boning e- (most EN atoms 1st)

           Any extra e- are added to CA

5. Add additional bonds to get formal charges as close to zero as possible (sum of formal charges must equal the charge of the ion or zero if its a neutral molecule)

​

Exceptions

​

H : 2 valance e- 

Group 3: incomplete octets (6/8)

≥Period3 : can expand their octets using d orbitals
