The electronegativity difference between Mg and Br is approximately 1.0. Mg has an electronegativity value of around 1.2, while Br has an electronegativity value of around 2.8. This difference in electronegativity indicates that a bond between Mg and Br would have a somewhat polar character.
Fluorine has the most electronegative element, Cl and Br
Mg (magnesium) has the lowest electronegativity among Ba, Ca, Mg, and Sr.
Ionic- the difference in electronegativity is high (Mg 1.31, Cl 3.16)
MgF2 is considered ionic because it is composed of a metal (Mg) and a nonmetal (F) which typically form ionic bonds due to the large difference in electronegativity between the two elements.
Mg and F are more likely to form an ionic compound because magnesium tends to lose 2 electrons to achieve a stable octet, while fluorine tends to gain 1 electron. This difference in electronegativity leads to the formation of an ionic bond between Mg and F. The other pairs do not exhibit as significant of an electronegativity difference to form an ionic compound.

A Grignard reagent or Grignard compound is a chemical compound with the generic formula R−Mg−X, where X is a halogen and R is an organic group, normally an alkyl or aryl. Two typical examples are methylmagnesium chloride Cl−Mg−CH3 and phenylmagnesium bromide (C6H5)−Mg−Br. They are a subclass of the organomagnesium compounds.
