Write Lewis dot symbols for (a) fluoride ion (F^–), (b) potassium ion (K⁺), and (c) sulfide ion (S^2-).

Strategy Starting with the Lewis dot symbol for each element, add dots (for anions) or remove dots (for cations) as needed to achieve the correct charge on each ion. Don’t forget to include the appropriate charge on the Lewis dot symbol.

Setup The Lewis dot symbols for F, K, and S are $:\overset{..}{\underset{..}{F}}⋅, K⋅, and ⋅\overset{..}{\underset{..}{S}}⋅$ respectively.
