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.

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.

Answer

Brief Explanations:

Magnesium has chemical symbol Mg and 2 valence electrons. In an electron - dot diagram, the 2 valence electrons are usually placed on different sides of the symbol (or can be on top). The given diagram has only 1 dot and incorrect dot placement. Also, magnesium's symbol is not Mn.

Answer:

No, because magnesium has two valence electrons. No, because both of the dots should be on top of the chemical symbol.
