Question

does the model correctly represent the electron dot diagram of magnesium? why or why not? select two options. mg· 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.

Explanation:

Magnesium's chemical symbol is Mg (correct), and it has 2 valence electrons (Group 2). The electron dot diagram shows 2 dots, matching its valence electrons.

Answer:

Yes, because the chemical symbol of magnesium is Mg., Yes, because magnesium has two valence electrons.
