The ratio of metal cationic (+) atom to nonmetal anionic (-) atom in the compound is 1:2.

What is electron configuration?

The term electron configuration shows the arrangement of electrons in an atom. We have the configurations of the atoms as follows;

magnesium - 1s22s22p63s2

bromine - 1s22s22p63s23p64s23d104p5

We can see that the catio is Mg^2+ and the anioin is Br^- hence  the ratio of metal cationic (+) atom to nonmetal anionic (-) atom in the compound is 1:2.
