Answer: Lewis dot structures aren't drawn for ionic compounds, such as MgCl2. Because there aren't any shared electron pairs in an ionic compound. Lewis structure are only drawn for molecular compounds, atoms, or some individual ions. If we want to visualize a chloride ion (Cl -), it's Lewis structure will show Cl with complete octet.
