Draw one Lewis structure that obeys the octet rule of XO3^-2. Draw one Lewis structure that best minimizes the formal charge of XO3^-2 (label all non-zero formal charges by each atom).
Added by Amparo S.
Step 1
Oxygen has 6 valence electrons, and there is one oxygen atom in XO3^-2, so we have 6 valence electrons. Additionally, the charge of -2 means we need to add 2 more electrons. Total valence electrons = 6 (from oxygen) + 2 (from the charge) = 8 electrons ** Show more…
