Step 1: Draw the Lewis structure for ClO^3−, starting with the central atom (Cl).
Place three O atoms around the Cl atom, ensuring each O atom has a single bond with the Cl atom.
Step 2: Add remaining valence electrons to complete the octet for each O atom.
O has 6 valence electrons, so add 3 electrons to each O atom (6 in total, since one electron is used in the single bond with Cl).
Final Answer
The Lewis structure for ClO^3− is: Cl—O—O | O The formal charge for the central atom (Cl) is + 5.
