Question:

Draw and explain the Lewis structure of the most important resonance form of the ion {eq}AsO_4^{3-} {/eq}. Show the formal charges and oxidation numbers of the atoms.

Lewis Structures:

The most important Lewis structure for a compound or an ion containing more than one possible Lewis structures, or a major resonance contributor, is determined based on:

  • Minimizing the formal charges of the particles involved.
  • Obeying the octet rule.
  • Placing negative formal charges on more electronegative atoms.
