Two - MgCl2
magnesium has 2 outer electrons, its valence is 2+ sodium has 1 outer electrons, its valence is 1+
Since fluorine and chlorine are in family 7A, they each have 7 valence electrons. The number of the family corresponds to the number of valence electrons.
7
There are 2 electrons in the valence orbital of a Magnesium atom.

Ionic because in a dot diagram Magnesium has 2 valence electrons and chlorine has 7 valence electrons. With 2 chlorine atoms there are two spots for electrons to jump over because each chlorine atom has room for one more electron and so both of magnesium's valence electrons would jump over to either chlorine. I hope this helped!
Two - MgCl2
