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. In an electron - dot diagram, magnesium has 2 valence electrons which should be represented as two dots around the symbol. The given diagram has only one dot. Also, the dots can be placed on any of the four sides (top, bottom, left, right) of the symbol, not necessarily on top.

Answer:

No, because magnesium has two valence electrons.
No, because both of the dots should be around the chemical symbol (not just one as shown).
