Step 1:I'll solve this step-by-step using proper LaTeX formatting:
Step 2:: Determine the Lewis structure of the chlorate ion
- The chlorate ion ($$ClO_{3}^{-}$$) consists of one chlorine atom and three oxygen atoms
- The overall charge is - 1
Step 3:: Calculate the number of valence electrons
- Total valence electrons: $$7 + 18 + 1 = 26$$ electrons
- Chlorine (Group 17): 7 valence electrons - Oxygen (Group 16): 6 valence electrons × 3 = 18 electrons - Negative charge adds 1 electron
Step 4:: Calculate the formal charge using the formula:
- $$B$$ = number of bonding electrons
Where:
Step 5:: Calculate formal charge for chlorine
\text{Formal Charge}_{\text{Cl}} = 7 - 2 - \frac{6}{2} = 7 - 2 - 3 = +1
- Valence electrons for chlorine: 7 - Non-bonding electrons on chlorine: 2 - Bonding electrons: 6
Final Answer
The formal charge on the chlorine atom in the chlorate ion is + 1.
