Does the model correctly represent the electron dot diagram of magnesium? Why or why not? Select two options. M g with 1 dot above and 1 right. Yes, because the chemical symbol of magnesium is Mg. No, because the chemical symbol of magnesium is Mn. Yes, because magnesium has two valence electrons. No, because magnesium has seven valence electrons. No, because both of the dots should be on top of the chemical symbol.
