Well, if the these are NEUTRAL atoms, then we gots #"magnesium fluoride."#

Explanation:

......#Z=12#, and #Z=9#, respectively. Why? Because in the neutral atom there are an equal number of protons, positively charged nucular particles, and electrons, negatively charged EXTRA-nuclear particles.

And so a quick glance at the Periodic Table tells us that we got #Mg, Z=12#, and #F, Z=9#, respectively. And since these commonly form dication, and monoanion respectively, by addition or subtraction of electrons, we gots......#MgF_2#.
