5 pts
Draw a model that shows how magnesium and chlorine combine to form a bond.

Start with the electron dot structure for magnesium and chlorine, then use a series of 2 or more drawings to show the electron movement (please note that there maybe more than 1 atom for either magnesium and chlorine).

Use any model appropriate for the bond type.
