A student made the Lewis dot diagram of a compound as shown.
Student's Lewis Dot Model


What is the error in the Lewis dot diagram?
O The number of dots around CI should be six because it is receiving two electrons from Mg.
O The number of dots around Mg should be one because there is only one Cl around Mg atom.
O Another Cl should be shown around Mg that will transfer its unpaired electron to Mg.
O Another CI should be shown around Mg that will receive the second electron on Mg.
