Step 1: Determine the central atom in this molecule.
Iodine (EN = 2.5) is less electronegative than oxygen (EN = 3.5) and H can only make 1 bond, so iodine is the central atom.
Step 2: Calculate the total number of valence electrons present.
Group Valence Electrons
H 1A 1 × 1 e– = 1 e–
Cl 7A 1 × 7 e– = 7 e–
O 6A 4 × 6 e– = 24 e–
Total: 32 valence e–
Step 3: Draw the Lewis structure for the molecule.
The incomplete Lewis structure is:
Draw the structure of periodic acid, HIO4. Optimize formal charges.
