Question
A student drew this incorrect Lewis structure for $\mathrm{ClO}_{3}^{-}$. What errors were made when determining the number of valence electrons?
Step 1
Chlorine has 7 valence electrons, each oxygen atom has 6 valence electrons, and the extra electron from the negative charge gives us a total of 7 + 3*6 + 1 = 26 valence electrons. Show more…
