What is the formula for the ionic compound formed by Mg2+ and Se2-?

Question:

What is the formula for the ionic compound formed by {eq}Mg^{2+} {/eq} and {eq}Se^{2-} {/eq}?

Ionic Compounds:

To predict the formulas for ionic compounds, we use the valencies of the anion and cation. The smallest whole-number proportion that gives the neutral compound gives the ionic compound.
