Lewis Dot Structures

•  
• (1). Place the nuclei in the proper geometry.
• (2). Determine the total number of valence
  electrons.
• (3). Draw single bonds between the bonded pairs
  of atoms.
• (4). Fill in the remaining electrons as lone
  pairs without exceeding an octet on each heavy
  atom or a duet on H or He.
• (5). If any atoms do not have a completed octet,
  then move lone pairs to complete the octets by
  forming multiple bonds.
• (6). If several non-equivalent structures are
  possible, the lowest energy structure minimizes
  the formal charges.
• (7). Place the largest negative formal charges on
  the most electronegative atoms.
• (8). Use expanded octets on 3rd and 4th period
  elements only if necessary to accommodate the
  required total number of electrons.
• (9). Show the overall ionic charge in the final
  structures.
